MultiRAE monitors offer an industry-leading selection of interchangeable field-replaceable electrochemical, combustible, infrared, PID (photoionization detector), and gamma radiation sensors to fit a wide variety of applications. The MultiRAE family’s wireless capability elevates worker protection to the next level by providing safety officers real-time access to instrument readings and alarm status from any location for better visibility and faster response. Notes:  NDIR combustible sensors are not supported on the diffusion version with CSA certification.  The PID sensor requires a pumped configuration.  If a %Vol. NDIR sensor is installed in an instrument, a catalytic bead %LEL sensor must also be installed in the instrument for CSA certification. 8  MultiRAE User’s Guide 2.1 Key Features  All-in-one continuous monitoring capabilities for gamma radiation, VOCs, oxygen, toxic and combustible gases, for a total of up to six threats at a time  Highly customizable with over 25 field-interchangeable intelligent sensor options  Wireless access to real-time instrument readings and alarm status from any location through ProRAE Guardian Real-Time Wireless Safety System  Unmistakable five-way local and remote wireless notification of alarm conditions, including Man Down Alarm  Large graphical display with easy-to-use, icon-driven user interface  Simple maintenance with easily accessible sensors, pump, and plug-and-play battery  Fully automated charging, data management, bump testing and calibration with AutoRAE 2 MultiRAE With Pump, front view MultiRAE Lite Diffusion Model, rear view External filter Gas inlets Alarm LEDs Gas inlet Belt clip (on back) Display [MODE] key [N/-] key [Y/+] key Alarm Buzzer Alarm Alarm LED Alarm LEDs Buzzer LED Note: The front of the diffusion model Charging and of the MultiRAE Lite is the same as the Communication pumped model, but instead of a single Contacts gas inlet at the top, there are five inlets on the back side, as well as an extra alarm buzzer and LEDs. The belt clip on the back of the pump-equipped MultiRAE can be swiveled for carrying it at different angles. 9  MultiRAE User’s Guide 3 User Interface The MultiRAE’s user interface consists of the display, alarm LEDs, an alarm buzzer, and three keys. 3.1 Display Overview The LCD display provides visual feedback that includes the sensor types, readings, alarm status, battery condition, and other information. “All sensors tested and calibrated according to policy” tick mark Man Down alarm Sensor due for a bump test enabled Wireless radio on/off statusand signal strength Status indicators Sensor type Sensor due for calibration Unit of measure Alarm type (High, Sensor-specific Low, etc.) additional information (PID lamp type, Reading measurement gas, correction factor, etc.) Soft keys (functions change by activity) 3.1.1 Status Indicator Icons Along the top of most screens are status indicators that tell you whether a function is operating and/or its strength or level. Icon Function Wireless status: the radio is on Wireless status: the radio is off The instrument is not equipped with a radio (no icon) Wireless strength (0 to 5 bars) Pump status (only on pump-equipped models) Datalogging status (shown when datalogging is on, blank when off) Battery status (three segments show battery charge level) Man Down alarm enabled Sensor due for calibration Sensor due for a bump test “All sensors tested and calibrated to policy” tick mark (all sensors have been bump tested and calibrated; no sensor is overdue for a bump test or calibration according to the intervals configured on the instrument) 10  MultiRAE User’s Guide 3.1.2 Keys And Interface The MultiRAE has three keys: Y/+ MODE N/- In addition to their labeled functions, [Y/+], [MODE], and [N/-] act as “soft keys” that control different parameters and make different selections within the instrument’s menus. From menu to menu, each key controls a different parameter or makes a different selection. Three panes along the bottom of the display are “mapped” to the keys. These change as menus change, but at all times the left pane corresponds to the [Y/+] key, the center pane corresponds to the [MODE] key, and the right pane corresponds to the [N/-] key. Here are examples that show the relationships of the keys and functions: In addition to the functions described above, any of the keys can be used to manually activate display backlighting. Press any key when the backlighting is off to turn it on. A subsequent key press is required to carry out an actual function corresponding to that key. 3.1.3 LCD Flip The MultiRAE senses its vertical/horizontal orientation, and can automatically flip the display 180 degrees, making it easy to read if the MultiRAE is upside down. (You can turn this feature on or off in Programming Mode, under “Monitor/LCD Flip.”) As the MultiRAE is tilted, the gravity sensor detects its orientation and inverts the screen when it is past its horizontal position. 11  MultiRAE User’s Guide 3.1.4 Key Remapping When LCD Is Flipped When the instrument is inverted and the LCD flips, the keys are remapped to the functions shown on the screen. Display with MultiRAE in non-inverted position: Display with MultiRAE inverted: 12  MultiRAE User’s Guide 3.2 Screen Display For Various Numbers Of Active Sensors The MultiRAE family of instruments can display readings from one to six sensors (including dual sensors), depending on the configuration. In order to maximize readability and the amount of information shown, the display is automatically reconfigured, according to the number and types of sensors in the MultiRAE. If the configuration includes five sensors, and one of them is a PID, then the lamp value (9.8eV or 10.6eV) is shown, along with the currently applied correction factor (CF) and measurement gas. One sensor. Two sensors. Three sensors. Four sensors. Five sensors, Five sensors, Six-sensor including Gamma including PID, configuration with radiation sensor. showing lamp type, CO+H2S combo correction factor, and sensor. measurement gas. 13  MultiRAE User’s Guide 3.3 Menus The reading menus are easy to step through by pressing the [N/-] key. Hygiene Mode: Sampling is continuous, and Hygiene Mode allows you to clear peak and minimum values at any time. Search Mode: Samples only when you tell it to sample. This allows you to save sample readings as individual events in the datalog. You can also clear peak and minimum values. Note: You can switch between Hygiene and Search modes via the Programming Menu (Select Monitor and then Operation Mode). Note: If the instrument is not equipped with a VOC sensor (PID), or is not equipped with an LEL sensor, then screens for those sensors (VOC Gas Status and LEL Gas Status, respectively) are not shown. Hygiene Mode Note: Dashed line indicates automatic progression. 14  MultiRAE User’s Guide Search Mode Notes:  If the instrument is not equipped with a VOC sensor (PID), or is not equipped with an LEL sensor, then screens for those sensors (VOC Gas Status and LEL Gas Status, respectively) are not shown.  If the Peak or Min is cleared, the Average is also cleared. In addition, each cycle through the main screen after they are cleared will route from “Ready… Start sampling?” directly to Date and Time if you press [N/-] (see red line in diagram below), until you perform a new sample. Also, if you start sampling again and stop sampling, clear the Peak, or clear the Min, it advances to Date and Time, as well. Note: Dashed line indicates automatic progression. 15  MultiRAE User’s Guide 4 Wireless Control And Submenus When you step through the main menu, as shown in the previous diagrams, there are screens for wireless communication. Note: These are only present if the MultiRAE is equipped with a wireless module. At the Radio On/Off screen, you can turn the radio on or off, if the MultiRAE is in Advanced User Mode. The radio turns off instantly, but turning on the radio takes a few seconds, so you see a screen that indicates the radio is being turned on. If the instrument is in Basic User Mode, the option for turning the radio on or off does not appear (you can turn it on or off in Programming Mode). At the Wireless screen, you can check communication with other wireless devices and get other useful information about the wireless settings. The Wireless menu is divided into a sequence of four “pages,” each presenting different information. As you press [Y/+] on each of the “pages,” you advance to the next one. Unit ID (unique identifier of the instrument’s radio), Pan ID, and Channel are read-only parameters that help you to check whether the instrument’s wireless settings are correct (very helpful for troubleshooting). The next “page,” Parent ID and Device Type are also read-only. The Parent ID (the ID of the “Parent” wireless device to which the monitor is connected) is not changeable. The device type tells you that it is “Standard,” meaning it transmits and receives. The third “page” is labeled “Ping,” where you can check the signal strength via RSSI (received signal strength indication) and “ping” the network to confirm an active two-way communication network. Each time you press [MODE] to “ping” the network, a number of sends is included under “Sent.” If the network receives the signal and sends one back, which is in turn received by the MultiRAE, then a number is added under “Received.” The fourth “page” includes the type of transmitter (Region), Radio Type (model), and Tx Power (transmission power). These are primarily for diagnostics and troubleshooting. When you reach the fourth “page,” you can wrap around to the first one by pressing [Y/+]. Otherwise, you can press [N/-] to quit, which advances to the next screen. 16  MultiRAE User’s Guide 5 Battery Always make sure the batteries are fully charged before using the MultiRAE. Three battery options are available for the MultiRAE: 1. Standard duration rechargeable Li-ion battery (PN: M01-3053-000) 2. Extended-duration rechargeable Li-ion battery delivering 50% more runtime than the standard battery (PN: M01-3055-000) 3. Alkaline battery pack for four standard AA-sized batteries (PN: M01-3054-000) Its standard or extended-duration batteries are charged inside the instrument by placing the MultiRAE in its cradle or using the Travel Charger. Contacts on the bottom of the instrument meet the cradle’s contact pins, transferring power. Note: Before setting the MultiRAE into its MultiRAE Desktop Cradle or attaching its Travel Charger, visually inspect the contacts to make sure they are clean. If they are not, wipe them with a soft, dry cloth. Do not use solvents or cleaners. WARNING To reduce the risk of ignition of hazardous atmospheres, recharge, remove or replace the battery only in an area known to be non-hazardous! Do not mix old and new batteries or batteries from different manufacturers. 5.1 Charging With The MultiRAE Desktop Cradle Follow this procedure to charge the MultiRAE: 1. Plug the AC/DC adapter into the MultiRAE’s Desktop Cradle. 2. Plug the AC/DC adapter into the wall outlet. 3. Place the MultiRAE into the cradle (make sure the bottom of the instrument and the alignment pins on the cradle mate properly) and press down until it is locked in place. The MultiRAE begins charging automatically. The LED in the cradle should glow red to indicate charging. When charging is complete, the LED in the cradle glows green. To remove the MultiRAE from the Desktop Cradle, tilt it toward you until it releases, and then lift it up. Press down until MultiRAE is seated Release the firmly in the cradle MultiRAE by tilting it forward and lifting 17  MultiRAE User’s Guide Next, put the plug from the power supply into the jack on the side of the Desktop Cradle: Plug the other end of the charger into a power source. Automatic PID Lamp Cleaning When a MultiRAE equipped with a PID (photoionization detector) is placed in the Desktop Cradle, its PID is automatically cleaned. During the first four hours of charging, continuous lamp auto-cleaning is performed. After that, cleaning stops. The battery continues to be charged, if necessary. 5.2 Charging With The Travel Charger The Travel Charger is a lightweight portable alternative to the Desktop Cradle for charging and PC communications. Follow these steps to use the Travel Charger. Before attaching the Travel Charger, check that it is aligned correctly with the base of the MultiRAE. There are two alignment pins on one side and one alignment pin on the other side, designed to mate with matching points on the bottom of the MultiRAE: 1. Check bottom of MultiRAE 2.

The LEDs glow green when the battery is fully charged. 5.4 Charging With The AutoRAE 2 A MultiRAE’s battery can be charged by placing the monitor in an AutoRAE 2 Cradle. Details are covered in the AutoRAE 2 User’s Guide. 5.5 Replacing A Battery The MultiRAE battery packs are plug-and-play, and can be replaced on the go without tools. To replace the MultiRAE battery: 1. Remove the battery from the instrument by sliding the tab and tilting out the adapter. Note: The belt clip and rubber boot are removed in the illustration for clarity. They can be left on while replacing a battery. 2. Tilt a fully charged battery (or alkaline battery adapter) into the battery compartment and place it in the instrument. 3. Slide the tab back into place to secure the battery. 20  MultiRAE User’s Guide 5.6 Battery States The battery icon on the display shows how much charge is in the battery and alerts you to any charging problems. Full charge 2/3 charge 1/3 charge Low charge Battery alert When the battery’s charge falls below a preset voltage, the instrument warns you by beeping once and flashing once every minute, and the “empty battery” icon blinks on and off once per second. The instrument automatically powers down within 10 minutes, after which you will need to either recharge the battery, or replace it with a fresh one with a full charge. 5.7 Alkaline Battery Pack An alkaline battery adapter is supplied with each instrument. The adapter (part number M01-3054-000) is installed and removed just like the rechargeable battery. It accepts four AA alkaline batteries (use only Duracell MN1500) and provides approximately 8 hours of normal operation. Note: The vibration alarm is disabled whenever the alkaline adapter is used. To replace the alkaline adapter’s batteries: 1. Remove the hex-socket screw at the end of the adapter. 2. Lift the cover off the battery compartment. 3. Insert four fresh AA batteries as indicated by the polarity (+/-) markings. 4. Replace the cover and replace the hex screw. IMPORTANT! Alkaline batteries cannot be recharged. The instrument’s internal circuit detects alkaline battery pack and will not allow recharging. If you try to charge alkaline batteries installed in the instrument, the Charging Cradle or Travel Charger’s charging LED does not glow, indicating that it will not charge them. The alkaline battery adapter accepts four AA alkaline batteries (use only Duracell MN1500). Do not mix old and new batteries or batteries from different manufacturers. Note: When replacing alkaline batteries, properly dispose of old ones. 21  MultiRAE User’s Guide 6 Turning The MultiRAE On And Off 6.1 Turning The MultiRAE On With the instrument turned off, press and hold the [MODE] key until the beep sounds and the display and LED alarm lights turn on, and then release. A RAE Systems logo (or a company name) should appear first. This is followed by a progression of screens that tell you the MultiRAE’s current settings:  Product name and model number, air flow type, and serial number  Application firmware version, build date, and build time  Sensor firmware, build date, build time  Installed sensors (including serial number/production/expiration/calibration date and alarm limit settings)  Current date, time, temperature, and relative humidity  User mode and operation mode  Battery type, voltage, shutoff voltage  Alarm mode and alarm settings  Datalog period (if it is activated) and interval  Policy Enforcement settings (whether calibration and/or bump testing are enforced) Note: To speed up the startup time, the number of screens shown on startup can be reduced by enabling the Fast Startup option under Programming/Monitor. Then the MultiRAE’s main reading screen appears. It may take a few minutes for sensors to show a reading, so if any have not warmed up by the time the main screen is shown, you will see “- - -” instead of a numerical value until the sensor provides data (typically less than 2 minutes). Then it displays instantaneous readings similar to the following screen (depending on the sensors installed) and is ready for use. Note: If the battery is completely empty, then the display briefly shows the message “Battery Fully Discharged,” and the MultiRAE shuts off. You should charge the battery or replace it with a fully charged battery before turning it on again. 6.2 Turning The MultiRAE Off Press and hold [MODE]. A 5-second countdown to shutoff begins. You must hold your finger on the key for the entire shutoff process until the MultiRAE is powered off. 22  MultiRAE User’s Guide 6.3 Testing Alarm Indicators Under normal-operation mode and non-alarm conditions, the buzzer, vibration alarm, LED, and backlight can be tested at any time by pressing [Y/+] once. IMPORTANT! If any of the alarms does not respond to this test, check the Alarm Settings in Programming Mode. It is possible that any or all of the alarms have been turned off. If all of the alarms are turned on, but one or more of them (buzzer, LED lights, or vibration alarm) does not respond to this test, do not use the instrument. Contact your RAE Systems distributor for technical support. 6.4 Pump Status IMPORTANT! During operation, make sure the probe inlet and the gas outlet are free of obstructions. Obstructions can cause premature wear on the pump, false readings, or pump stalling. During normal operation, the pump icon alternately shows inflow and outflow as shown here: If there is a pump failure or obstruction that disrupts the pump, the alarm sounds and you see this icon blinking on and off: Once the obstruction is removed, you can try to restart the pump by pressing the [Y/+]. If the pump does not restart, and the pump stall alarm continues, consult the Troubleshooting section of this guide or contact RAE Systems Technical Support. It is advisable to perform a pump stall test periodically, to make sure the pump is working properly and there are no leaks in the system. To perform a pump stall test, simply block the gas inlet with your finger. To pass the test, the instrument should go into a pump alarm. Press [Y/+] to disable the alarm and return to normal operation. Note: Pump Status is not indicated on diffusion MultiRAEs. 6.5 Calibration Status The instrument displays this icon next to the sensor that requires calibration: Calibration is required (and indicated by this icon) if:  The lamp type has been changed (for example, from 10.6 eV to 9.8 eV).  The sensor module has been replaced with one whose calibration is overdue.  The defined period of time between calibrations has been exceeded.  If you have changed the calibration gas type without recalibrating the instrument.  The sensor has failed a previous calibration. 23  MultiRAE User’s Guide 6.6 Bump Status The instrument displays this icon next to the sensor that requires bump test: A bump test is required (and indicated by this icon) if:  The defined period of time between bump tests has been exceeded (bump test overdue).  The sensor has failed a previous bump test.  The sensor(s) should be challenged on a periodic basis. 24  MultiRAE User’s Guide 7 Modes Of Operation The MultiRAE has two operation modes and two user modes. 7.1 Hygiene Operation Mode Hygiene Mode provides continuous monitoring. 7.2 Search Operation Mode Search Mode provides monitoring only when monitoring is initiated. This allows specific samples to be taken at different times, rather than continuously. 7.3 Basic User Mode In Basic User Mode, some restrictions are applied, including password protection that guards against entering Programming Mode by unauthorized personnel. 7.4 Advanced User Mode In Advanced User Mode, there are no access restrictions (you do not need a password), and MultiRAE provides the indications and data you need most for typical monitoring applications. 8 Programming The menu in Programming Mode is to adjust settings, calibrate sensors, and initiate communication with a computer. It has the following submenus:  Calibration  Measurement  Alarms  Datalog  Wireless  Monitor 8.1 Enter Programming In Advanced Mode 1. To enter Programming Mode, press and hold [MODE] and [N/-] until you see the Calibration screen. No password is necessary in Advanced Mode. 2. Press [N/-] to step through the programming screens. To enter a menu and view or edit parameters in its submenus, press [Y/+]. 25  MultiRAE User’s Guide 8.2 Enter Programming In Basic Mode 1. To enter Programming Mode, press and hold [MODE] and [N/-] until you see the Password screen. 2. Input the 4-digit password:  Increase the number from 0 through 9 by pressing [Y/+].  Step from digit to digit using [N/-].  Press [MODE] when you are done. If you make a mistake, you can cycle through the digits by pressing [N/-] and then using [Y/+] to change the number in each position. Note: The default password is 0000. Note: The password screen only appears when you enter the Programming Mode the first time after turning the instrument on in Basic Mode. If you have input the correct password, you do not have to input it again to enter Programming Mode until you turn the instrument off and on again. Once you enter Programming Mode, the Calibration menu is highlighted. Press [N/-] to step through the programming screens. To enter a menu and view or edit parameters in its submenus, press [Y/+]. 26  MultiRAE User’s Guide 8.3 Menus And Submenus In Programming Mode, menus and submenus are organized as shown here: Calibration Measurement Alarms Datalog Wireless* Monitor Fresh Air Sensor On/Off Alarm Limits Clear Datalog Radio ON/OFF LCD Contrast Multi Sensor Change Meas.

Change Span2 Value menu item is only shown if a 3-point calibration is enabled on the instrument. Three-point calibration is disabled by default, but can be enabled on MultiRAE and MultiRAE Pro instruments with 10.6eV PID sensors, including high-range ppm and ppb PID sensors. The MultiRAE Lite PID sensor only supports 2-point calibration. 8.3.1 Editing And Selecting Parameters And Sensors There are a few basic ways to edit parameters, select sensors, and perform other activities in the MultiRAE. The actions performed by pressing keys always match 1-to-1 with the boxes along the bottom of the display and the three keys. Some parameters are edited by scrolling and selecting individual items (black bars behind white text act as highlighters). Some include a choice via “radio buttons,” where only one item in a list can be selected, while other menus use boxes for you to “check” with an “X,” and these allow for multiple items in a list to be selected. In all cases of editing, you can save or undo your choice. 27  MultiRAE User’s Guide 8.3.2 Calibration Use this menu to perform a bump test or zero or span calibration for one or more sensors, and change the gas concentration value used in bump tests and span calibration, as well as choose which sensors will be calibrated at the same time. 8.3.2.1 Fresh Air This procedure determines the zero point of the sensor calibration curve for all the sensors that require a zero calibration. For the oxygen sensor, Fresh Air calibration sets the point equal to the concentration of oxygen in ambient air (approximately 20.9% volume). Note: Fresh air calibration is performed on all enabled gas sensors at the same time. To perform Fresh Air calibration on multiple sensors: 1. If using dry air, install the calibration adapter and connect it to a source of dry air. Otherwise do not use calibration adapter to perform fresh air calibration. 2. At the Calibration Menu, select “Fresh Air.” Press [Y/+] once to enter the fresh air calibration sub- menu. 3. Start the flow of dry air, if used. 4. Press [Y/+] to start fresh air calibration. 5. A countdown screen appears. You can abort the calibration at any time during the countdown by pressing [N/-]. Note: Dotted line indicates automatic progression. 6. If the calibration is not aborted, the display shows the sensor names and tells you whether the fresh air calibration passed or failed, followed by the sensors’ fresh air readings. 28  MultiRAE User’s Guide 8.3.2.2 Multi Sensor Span Depending on the configuration of your MultiRAE and span gas you have, you can perform a span calibration simultaneously on multiple sensors. You can define which sensors are calibrated together using the Multi Cal Select menu described in section 8.3.2.9. In case all sensors in the instrument cannot be calibrated with the same gas, the MultiRAE will intelligently split the span calibration process into several steps and will provide menu prompts accordingly. 1. At the Calibration Menu, select “Multi Sensor Span.” 2. Install the calibration adapter and connect it to a source of calibration gas. 3. Start the flow of calibration gas. 4. Press [Y/+] to start calibrating or wait for calibration to start automatically. 5. A countdown screen is shown. You can abort the calibration at any time during the countdown by pressing [N/-]. Note: Dotted line indicates automatic progression. 6. If the calibration is not aborted, the display shows the sensor names and tells you whether the calibration passed or failed, followed by the sensor readings. 8.3.2.3 Single Sensor Zero This allows you to perform zero (fresh air) calibration on individual sensors. Even though most toxic gas sensors can be zeroed in fresh air, sensors such as the CO2 and parts-per-billion PID sensor for volatile organic compounds (VOCs) should not be zeroed in fresh air. Both CO2 gas and VOCs are normally present in ambient air, so zeroing these sensors in ambient air will not allow for a true zero to be set for such sensors. The CO2 sensor should be zeroed in 99.9% nitrogen, and the parts-per-billion PID sensor with ambient air using a charcoal filter or a VOC zeroing tube. 1. If you are using a charcoal filter, connect it to the instrument. 2. If you are using dry air, install the calibration adapter and connect it to a source of dry air. 29  MultiRAE User’s Guide 3. At the Calibration Menu, select “Single Sensor Zero.” Press [Y/+] once to enter the zero calibration sub-menu. 4. Start the flow of dry air, if used. 5. Press [Y/+] to start zero calibration. 6. A countdown screen appears. You can abort the calibration at any time during the countdown by pressing [N/-]. Note: Dotted line indicates automatic progression. 7. If the calibration is not aborted, the display shows the sensor names and tells you whether the zero calibration passed or failed, followed by the sensors’ zero calibration readings. 8.3.2.4 Single Sensor Span Instead of performing a span calibration on multiple sensors simultaneously, you can select a single sensor and perform a span calibration. Note: If a calibration icon (bottle with bottom portion filled in) is shown next to any of the sensors, it means that the sensor is due for a full calibration. To perform span calibration of an individual sensor, follow these steps: 1. At the Calibration Menu, select “Single Sensor Span.” 2. Select a sensor to calibrate from the list. 3. Install the calibration adapter and connect it to a source of calibration gas. 4. Verify that the displayed calibration value meets the concentration specified on the gas cylinder. 5. Start the flow of calibration gas. 6. Press [Y/+] to start calibrating or wait for calibration to start automatically. 30  MultiRAE User’s Guide 7. A countdown screen appears. You can abort the calibration at any time during the countdown by pressing [N/-]. Note: Dotted line indicates automatic progression. 8. If the calibration is not aborted, the display shows the sensor names and tells you whether the calibration passed or failed, followed by the sensor readings. Note: The gamma radiation sensor comes pre-calibrated from the factory and does not require routine calibration. However, you can check it by placing a check-source on the rear of the MultiRAE equipped with a gamma sensor to check the readings. There is a raised dot on the rubber boot that marks where the sensor is located inside the instrument. 8.3.2.5 Multi Sensor Bump Depending on the configuration of your MultiRAE and span gas you have, you can perform a bump test simultaneously on multiple sensors. Which sensors are bump tested simultaneously is defined in the Multi Cal Select menu. Refer to section 8.3.2.9 for more information. In case all sensors in the instrument cannot be calibrated with the same gas, the MultiRAE will intelligently split the span calibration process into several steps and will provide menu prompts accordingly. 1. At the Calibration Menu, select “Multi Sensor Bump.” 2. Install the calibration adapter and connect it to a source of calibration gas. 31  MultiRAE User’s Guide 3. Start the flow of calibration gas. 4. Press [Y/+] to start calibrating or wait for calibration to start automatically. 5. A countdown screen is shown. You can abort the calibration at any time during the countdown by pressing [N/-]. Note: Dotted line indicates automatic progression. 6. If the calibration is not aborted, the display shows the sensor names and tells you whether the calibration passed or failed, followed by the sensor readings. 7. If a sensor requires different gas (such as a PID for VOCs), you are prompted. Change the calibration gas, and when you are ready, start bump testing by pressing [Y/+]. Note: You can quit the bump calibration procedure and exit to the menu whenever you see “Quit.” Press [MODE] to quit. 32  MultiRAE User’s Guide 8.3.2.6 Single Sensor Bump This menu allows a bump test to be performed on an individual sensor of your choice. Note: If a bump test icon (bottle with bottom portion not filled in) is shown next to any of the sensors, it means that the sensor is due for a bump test. To perform a bump test on an individual sensor, follow these steps: 1. At the Calibration Menu, select “Single Sensor Bump.” 2. Scroll down the list using [N/-], and then press [Y/+] to select a sensor to calibrate. 3. Install the calibration adapter and connect it to a source of calibration gas. 4. Verify that the displayed calibration value meets the concentration specified on the gas cylinder. 5. Start the flow of calibration gas. Important! After each sensor is bump tested, and you press “OK,” the next sensor in the menu list is highlighted. Note: Dotted line indicates automatic progression. 6. Press [Y/+] to start calibrating or wait for calibration to start automatically. 7. A countdown screen appears. You can abort the calibration at any time during the countdown by pressing [N/-]. 8. If the calibration is not aborted, the display shows the sensor names and tells you whether the calibration passed or failed, followed by the sensor readings. 33  MultiRAE User’s Guide 8.3.2.7 Cal. Reference It is sometimes desirable to calibrate a sensor (PID for VOC, and LEL) with a specific gas for best response to a gas you are surveying. The Cal. Reference library contains calibration curves for the PID and LEL sensors for select gases. Choose the sensor, and then select from the list of reference gases. 8.3.2.8 Change Cal. Gas You can change the calibration gas for the MultiRAE’s PID and LEL sensors. Select from a custom list that you create (My List), the last ten gases used, the built-in gas library for your PID lamp, and user-defined custom gases. Each gas is shown in the list for selection and the screen automatically changes to show its full name, chemical formula, molecular weight (M.W.) and correction factor (CF). 8.3.2.9 Multi Cal Select This menu allows you to define a group of sensors to be bump tested and span calibrated together. Simultaneous testing and calibration of multiple sensors shortens the bump test and calibration processes and reduces the number of individual gas cylinders you need. For example, it may be more efficient to use a single cylinder with a four-gas mix including 50% LEL Methane, 18% O2, 10 ppm H2S, and 50 ppm CO, to calibrate the LEL, O2, CO, and H2S sensors at one time, compared to using four distinct gas cylinders and calibrate these sensors individually in sequence. In order for sensors to be calibrated together, all of them must be selected using Multi Cal. Select. 1. Scroll down the list of sensors using the [N/-] key. 2. Add or remove that gas from the list by pressing [Y/+]. An “X” in a box to the left of a sensor’s name indicates it is selected. 3. Once you have made all your selections, press [MODE] for “Done.” 34  MultiRAE User’s Guide 8.3.2.10 Change Span Value You can individually set the span gas concentration for each sensor. This concentration setting will also be used for a bump test. The units of measure (ppm, %LEL, etc.) are shown on the display. 1. Scroll down the list of sensors using the [N/-] key. 2. Press [Y/+] to select it. 3. Press [N/-] to step through the digits. 4. Press [Y/+] to increase the number from 0 through 9. Once the number 9 is reached, pressing [Y/+] causes the numbers to “wrap around” to 0 and count up again. 5. Once you have set the desired value, press [MODE] for “Done.” This registers the new span value. 8.3.2.11 Change Span2 Value If your MultiRAE is equipped with a high-range, or parts-per billion, PID sensor, you can set the span gas value for a third calibration point (Span2). The unit of measure is shown on the display. 1. Press [Y/+] to select the highlighted sensor (VOC). 2. Press [N/-] to step through the digits. 3. Press [Y/+] to increase the number from 0 through 9. Once the number 9 is reached, pressing [Y/+] causes the numbers to “wrap around” to 0 and count up again. 4. Once you have set the desired value, press [MODE] for “Done.” This registers the new Span 2 value. Note: Three-point calibration is disabled by default, but can be enabled on MultiRAE and MultiRAE Pro instruments with 10.6eV PID sensors, including high-range ppm and ppb PID sensors. The MultiRAE Lite PID sensor only supports 2-point calibration. 35  MultiRAE User’s Guide 8.3.3 Measurement The submenus for Measurement include Sensor On/Off, Change Measurement Gas, and VOC and Gamma (if equipped) Measurement Units. 8.3.3.1 Sensor On/Off You can turn sensors on or off via this submenu. An “X” in a box to the left of a sensor’s name indicates it is turned on. 1. Scroll down the list of sensors using the [N/-] key. 2. Add or remove that gas from the list by pressing [Y/+]. An “X” in a box to the left of a sensor’s name indicates it is selected. 3. Once you have made all your selections, press [MODE] for “Done.” 8.3.3.2 Change Meas. Gas The MultiRAE has extensive onboard gas libraries for combustible gases and VOCs that you can use to configure your MultiRAE to automatically apply the appropriate correction factors and produce readings in the units of the desired combustible gas or VOC. 36  MultiRAE User’s Guide Measurement gases are organized in four lists:  My List is a customized list of gases that you create. It contains a maximum of 10 gases and can only be built in ProRAE Studio II on a PC and transferred to the instrument. Note: The first gas in the list is always isobutylene (it cannot be removed from the list).  Last Ten is a list of the last ten gases used by your instrument. The list is built automatically and is only updated if the gas selected from Custom Gases or Library is not already in the Last Ten. This ensures that there is no repetition.  Gas Library is a library that consists of more than 200 gases for the PID sensor and more than 50 for the catalytic LEL sensor.  Custom Gases are gases with user-modified parameters. Using ProRAE Studio II, all parameters defining a gas can be modified, including the name, span value(s), correction factor, and default alarm limits. 37  MultiRAE User’s Guide 8.3.3.3 Measurement Units In some cases, the measurement unit for displaying data from sensors can be changed. Standard available measurement units include: Abbreviation Unit Sensor Type ppm, ppb parts per million, parts per billion PID for VOC mg/m3, ug/m3 milligrams per cubic meter, micrograms per cubic meter PID for VOC ppm, mg/m3 parts per million, milligrams per cubic meter EC (electrochemical) ppm Only, %VOL only, parts per million, percent by volume, automatically CO2 Auto Range switch from ppm to %VOL at 10,000 ppm and higher* urem, mrem microrems and millirems Gamma uSv, mSv microSieverts and milliSieverts Gamma uR, mR microRoentgens and milliRoentgens Gamma uGy, mGy microGrays and milliGrays Gamma * The CO2 switch point from ppm to %VOL can be changed via ProRAE Studio 2. Here are two examples of menu hierarchies (select the sensor type and then the measurement unit): 8.3.4 Alarms Use this menu to change high, low, STEL, and TWA alarm limits - the points at which alarms are triggered. The Alarms menu also allows changing alarm mode (latched or automatic reset) and alarm output methods (combinations of light, buzzer, and vibration alarm indications). 8.3.4.1 Alarm Limits There are four groups of alarm settings that you can adjust for each individual sensor for which a particular alarm type is available. Settings:  High Alarm  Low Alarm  STEL (Short-Term Exposure Limit) Alarm  TWA (Time-Weighted Average) Alarm Note: Some alarm settings are not applicable to all sensors. If a setting is irrelevant to a sensor (for example, STEL for a gamma radiation sensor), then that sensor does not appear in the list. 38  MultiRAE User’s Guide 8.3.4.2 Alarm Mode You can program the MultiRAE so that there are two ways to shut off an alarm: Auto Reset When the alarm condition is no longer present, the alarm stops automatically. Latch You must manually turn off an alarm when one is triggered. The latched setting only controls alarms for High Alarm, Low Alarm, STEL Alarm, and TWA Alarm. 8.3.4.3 Alarm Settings You can enable/disable any combination of light (visible), buzzer (audible), and vibration alarms. Settings:  All Enabled  Light  Vibration  Buzzer  Buzzer & Light  Buzzer & Vibration  Vibration & Light  All Disabled 8.3.4.4 Comfort Beep A Comfort Beep is a single beep of the audible alarm at 60-second intervals that informs the person using the MultiRAE that it is functioning. It can be turned on or off. 8.3.4.5 Man Down Alarm The Man Down Alarm is a critical and potentially lifesaving feature of every MultiRAE. The Man Down Alarm is based on the premise that if the instrument is motionless when it is not supposed to be, something wrong may be happening to its user. If that is the case, a wirelessly enabled MultiRAE not only goes into alarm locally on the instrument to notify people in the vicinity, but also remotely, over the RAE Systems Dedicated Wireless Network, to transmit the alarm to remote safety officers at a command center, that a person is down, so that help can be dispatched quickly. Whenever the Man Down feature is enabled, the main screen displays a Man Down icon along the top to indicate it is active: The MultiRAE has a 3D gravity sensor that can track the slightest motion of the instrument in any direction. If the instrument is not moved during that time, then a pre-alarm is activated to alert the user, and shows the “Are You OK?” screen. Pressing [Y/+] clears the alarm and returns the MultiRAE to its normal operation. Pressing [N/-] sets it into Man Down Alarm (and if wireless connectivity is enabled, a Man Down message is sent in real time to remote observers). If neither key is pressed, then after the count- down, it goes into Man Down Alarm (again sending a message to remote observers if wirelessly enabled). 39  MultiRAE User’s Guide Settings are available for:  Off/On (off by default)  Motionless Time: time the instrument is motionless before initiating a pre-alarm (30 seconds by default)  Motion Sensitivity: set to low, medium, or high to compensate for ambient vibration or motion (medium by default)  Warning Time: countdown, in seconds, from pre-alarm to Man Down alarm (30 seconds by default) When the Man Down pre-alarm is activated, the buzzer sounds and LEDs flash twice per second, and a countdown begins.  If the MultiRAE’s user presses [Y/+] for “Yes” in response to the “Are You OK?” question on the screen before the countdown reaches zero, the Man Down alarm stops and the main reading screen is displayed.  If the person does not press [Y/+] for “Yes” in response to the “Are You OK?” question on the screen before the countdown reaches zero, the Man Down alarm is triggered.  If the person presses [N/-] during the countdown, answering the “Are You OK?” question with “No,” the Man Down alarm starts. If wireless connectivity is enabled, a Man Down message is also sent to remote observers. IMPORTANT! When gas or radiation alarm conditions exist at the same time as the Man Down is activated, the pre- alarm stage is skipped and the instrument goes straight into a Super Alarm (gas or radiation and Man Down) with four beeps/flashes per second. 8.3.5 Datalog The instrument displays a floppy disk icon to indicate that a datalog is being recorded. The instrument stores the measured gas concentration for each sensor, date and time for each measurement, Site ID, User ID, and other parameters. The MultiRAE memory is sufficient to record six months’ worth of data for five sensors at one-minute intervals, 24/7. All data are retained (even after the unit is turned off) in non- volatile memory so that they can be downloaded at a later time to a PC. 8.3.5.1 Clear Datalog This operation erases all data stored in the datalog. Select “Clear Datalog,” and then “Yes.” Note: Once the datalog is cleared, the data cannot be recovered. 40  MultiRAE User’s Guide 8.3.5.2 Datalog Interval Intervals are shown in seconds. The default value is 60 seconds. The maximum interval is 3600 seconds, and the minimum is 1 second. 8.3.5.3 Sensor Selection You can choose which sensors’ data are included in the datalog. The entire list of installed sensors is shown, and you can individually select whether their data is included. Note: Turning a sensor off in the list does not change or erase its settings. 8.3.5.4 Data Selection Data Selection allows you to select which types of data are stored and made available when you download your datalog to a computer via ProRAE Studio II (version 1.04 or higher) software. You can choose any or all of four types of data (you must choose at least one):  Minimum  Average  Maximum  Real Time 8.3.5.5 Datalog Type The instrument offers three options for starting the datalogging process: Auto Automatically collects datalog information every time the instrument is sampling until the datalog memory is full. Manual Datalogging occurs only when you manually initiate it (see below for details). Snapshot Captures a single event when you press [MODE]. Note: You can only choose one datalog type to be active at a time. About Manual Datalogging When the instrument is set to Manual Datalog, you can turn datalogging on and off by repeatedly pressing [N/-] and stepping through the screens from the main display until you reach the screen that says “Start Datalog?”  When you reach the screen that says “Start Datalog?” press [Y/+] to start it. You see “Datalog Started,” confirming that datalogging is now on. You can turn it off by pressing [Y/+] again.  If datalogging is running, you can leave it running. However, if you want to turn it off, follow this procedure: Press [N/-] repeatedly to step through the screens until you reach the screen that says, “Stop Datalog?” Press [Y/+] to stop datalogging. The screen displays “Datalog Stopped” for a few seconds, before displaying “Start Datalog?” and the datalog interval. You can restart it anytime by pressing [Y/+] from that screen. 41  MultiRAE User’s Guide About Snapshot Datalogging When the instrument is in Snapshot datalogging mode, it captures a single “snapshot” of the data at the moment of your choosing. All you have to do is press [MODE] each time you want to capture a snapshot of the data at that instant. No snapshot. Press [MODE] for a snapshot. Datalog icon is shown momentarily during a snapshot 8.3.5.6 Memory Full Action When the internal datalog memory is full, the MultiRAE can either stop collecting data (Stop when full) or go back to the beginning and overwrite the data from the first entry, second entry, etc. (Wraparound). 8.3.6 Wireless When a MultiRAE is equipped with a wireless modem, its settings are controlled via the menu items under “Wireless.” 8.3.6.1 Radio ON/OFF Turn the radio on or off via this menu. 1. Choose between “On” and “Off” by pressing [N/-]. 2. Select the highlighted state by pressing [Y/+]. 3. Save or register the change:  Press [Y/+] to save the change.  Press [N/-] to undo the change. 42  MultiRAE User’s Guide 8.3.6.2 PAN ID The MultiRAE and any other devices that you want to interconnect wirelessly must have the same PAN ID. 1. Press [Y/+] to increase the number and [N/-] to advance to the next digit. 2. After moving to the last digit and making changes, press [MODE].  Press [Y/+] to save the change.  Press [N/-] to undo the change. 8.3.6.3 Channel The MultiRAE and any other devices that you want to interconnect wirelessly must be operating on the same channel. 1. Press [Y/+] to increase the number and [N/-] to advance to the next digit. 2. After moving to the last digit and making changes, press [MODE].  Press [Y/+] to save the change.  Press [N/-] to undo the change. 8.3.6.4 Join Network You can tell the MultiRAE to automatically join a network with a certain PAN ID without having to specify the communications channel. The PAN ID is shown for reference (if it is incorrect, you can change it, as described above). Press [Y/+] to join. 43  MultiRAE User’s Guide While it is searching for a network to join, the display shows this message: Joining Network Please Wait If it is unsuccessful, you will see this message: Failed To Join Network Check your other settings, as well as those of the network you are trying to join. You can press [Y/+] to retry or [N/-] to quit. 8.3.6.5 Interval This menu allows you to change the interval between wireless transmissions. The interval can be set to 10, 30, 60, 120, or 240 seconds. 1. Scroll down the list of intervals by pressing [N/-] until the interval you want is highlighted. 2. Select the highlighted interval by pressing [Y/+]. 3. Save or register the change:  Press [Y/+] to save the change.  Press [N/-] to undo the change. Note: The default interval is 30 seconds. 8.3.6.6 Off Network Alarm If you would like the MultiRAE to notify you when it loses connection with a network, turn this on. 1. Choose between “On” and “Off” by pressing [N/-]. 2. Select the highlighted state by pressing [Y/+]. 3. Register the change.  Press [Y/+] to save the change.  Press [N/-] to undo the change. 44  MultiRAE User’s Guide 8.3.6.7 Factory Reset Restore all the wireless settings to their original factory defaults. Caution! Once you reset the wireless settings, you cannot retrieve any of the settings deleted by performing this reset.  Press [Y/+] to reset the wireless settings.  Press [N/-] to exit without resetting the wireless settings. 8.3.7 Monitor The submenus under “Monitor” control the LCD’s contrast, operation mode, pump speed, and other parameters. Press [N/-] to advance through the submenus, and when you reach the last one, it returns to the first selection. 8.3.7.1 LCD Contrast The display’s contrast can be increased or decreased from its default setting. You may not need to ever change the default setting, but sometimes you can optimize the display to suit extreme temperature and ambient brightness/darkness conditions. Use the [Y/+] and [N/-] keys to decrease or increase LCD contrast, respectively (the bar graph aids in setting it). When you are done, press [MODE] to select “Done.” If you have not made a change, it exits to the submenu’s next selection. If you have made a change, you are prompted at the next screen to press [Y/+] to save the change or [N/-] to undo the change and exit to the next submenu selection. 45  MultiRAE User’s Guide 8.3.7.2 Operation Mode There are two operation modes, outlined below. Hygiene Mode When the MultiRAE is in Hygiene Mode, it continuously monitors, and if datalogging is on, it saves data continuously. Refer to page 25 for more information on operation in Hygiene Mode. Search Mode When the instrument is in Search Mode, it only samples when you activate sampling. When you see the display that says, “Ready…Start sampling?” press [Y/+] to start. The instrument automatically assigns a new Site ID to each measurement you take. The pump turns on and the instrument begins collecting data. To stop sampling, press [N/-] while the main display is showing. You will see a new screen that says, “Stop sampling?” Press [Y/+] to stop sampling. Press [N/-] if you want sampling to continue. Refer to page 25 for more information on operation in Search Mode. 8.3.7.3 Pump Speed If the MultiRAE is equipped with a pump, the pump can operate at two speeds, high and low. Running at low speed is quieter, extends pump lifespan, and conserves a small amount of power. There is almost no difference in sampling accuracy. 8.3.7.4 Zero At Start If your MultiRAE has been configured to perform a zero (fresh air) calibration upon startup, called Zero At Start, then the startup routine is interrupted so that you can perform a fresh air calibration for all sensors prior to using the instrument. If you do not want to perform a zero calibration, press [MODE] to bypass it. If you start a zero calibration and want to abort it, press [N/-], and the calibration stops and the main display is shown. 8.3.7.5 Fast Startup Fast Startup reduces the amount of time between when the instrument is turned on and is ready for use. It skips showing you many settings and is best suited to environments where the MultiRAE is turned on and off very often during a given day. If Fast Startup is not selected, then when the instrument starts, it shows you details of each sensor, including calibration information, high and low alarm
