The device enters pre-alarm when no motion is detected for 20 seconds. This condition can be cleared by moving the device. MotionAlert is turned OFF each time the device is powered OFF. After 30 seconds of no motion, the full MotionAlert alarm is triggered. This alarm can only be cleared by pressing the  button. This page displays if it was selected in Setup Mode. To activate or deactivate the MotionAlert feature, press the  button while the MOTIONALERT ACTIVATION page is displayed. 3.6 Sensor Missing Alarm Enabled PID and XCell sensors are continuously monitored for proper function. If, during operation, the PID or an XCell sensor is detected as failed or disconnected, this alarm message appears. "SENSOR MISSING" flashes on the display. The problematic sensor is indicated. The alarm sounds and the Fault and Alarm LEDs flash. The alarm can be silenced by pressing the  button; no other pages can be viewed. WARNING! When this alarm occurs, the device is inoperative for measuring gases. The user must exit the hazardous area, the device must be powered down, and the sensor situation must be corrected. 3.7 Monitoring Toxic Gases US The device can monitor the concentration of a variety of toxic gases in ambient air. Which toxic gases are monitored depends on the installed sensors. The device displays the gas concentration in parts per million (ppm), μmol/mol or mg/m3 on the Measuring page. Gas units are selected in the SETUP - INSTRUMENT OPTIONS page. WARNING! If an alarm is triggered while using the device, leave the area immediately.Remaining in the area under such circumstances can cause serious personal injury or death. The device has four gas alarms: HIGH Alarm LOW Alarm STEL Alarm TWA Alarm ALTAIR® 5X PID 24  Description Fig. 6 Alarm Conditions (here High Alarm) The carbon monoxide channel in the device is equipped with an internal filter. The purpose of this filter is to protect the CO sensor from acid gases (H2S, SO2, etc.) and from the hydrocarbons that the device is intended to measure, including the calibration gas, isobutylene. In normal use, an interferent signal for calibration or bump checking the device should not be observed on the CO channel. However, exposure to large amounts of certain hydrocarbons (either long exposure times or high concentrations) can overwhelm the filter and appear as signals on the CO channel. In normal operation, after the hydrocarbon exposure is ended, the filter is designed to outgas absorbed hydrocarbons at a rate that will not cause a signal on the CO channel. However, if the unit is exposed to high temperature (>40°C), this desorption rate increases and spurious signals may be observed on the CO channel due to gassing of previously absorbed hydrocarbons. Typically the CO sensor will recover within 24 hours but extremely high exposures can extend this time. After the recovery period if the CO sensor can no longer be calibrated or shows an elevated reading that cannot be brought to zero with a zero calibration, the CO sensor should be replaced. WARNING! Extremely high levels of VOCs will send the CO sensor into alarm and the sensor may not recover or the recovery period will be significant.  Take the impact on sensor performance into account when installing sensors. If the gas concentration reaches or exceeds the alarm set point or the STEL or TWA limits, the: alarm message displays and flashes in combination with the corresponding gas concentration backlight turns on US alarm sounds (if active) alarm LEDs flash (if active) vibrating alarm triggers (if active) 3.8 Monitoring Oxygen Concentration The device monitors the oxygen concentration in ambient air. The alarm set points can be set to acti- vate on two different conditions: Enriched - oxygen concentration > 20.8% or Deficient - oxygen concentration < 19.5%. While the device can detect up to 30% oxygen in the ambient air, it is approved for use only up to 21% oxygen-content. ALTAIR® 5X PID 25  Description WARNING! If an alarm activates while using the device, leave the area immediately. Remaining in the area under such circumstances can cause serious personal injury or death. When the alarm set point is reached for either of the above conditions: the alarm message displays and flashes in combination with the corresponding gas concentration backlight turns on alarm sounds (if active) alarm LEDs flash (if active) vibrating alarm triggers (if active) The LOW alarm (oxygen deficient) is latching and will not automatically reset when the O2 concentra- tion rises above the LOW set point. To reset the alarm press the  button. If the alarm is latching, the  button silences the alarm for five seconds. Alarms can be made latching or unlatching via MSA Link software. False oxygen alarms can occur due to changes in barometric pressure (altitude), humidity or extreme changes in ambient temperature. It is recommended that an oxygen calibration be performed at the temperature and pressure of use. Be sure that the device is in known fresh air before performing a calibration. 3.9 Monitoring Combustible Gases The device can be equipped with a catalytic combustible sensor that detects a variety of combustible gases up to 100 % LEL and displays the reading as either % LEL or % CH4. WARNING! If an alarm is triggered while using the device, leave the area immediately.Remaining in the area under such circumstances can cause serious personal injury or death. The catalytic combustible sensor has two alarm setpoints: HIGH Alarm LOW Alarm US If the gas concentration reaches or exceeds the alarm set point, the device: alarm message displays and flashes in combination with the corresponding gas concentration: backlight turns on alarm sounds (if active) alarm LEDs flash (if active) Gas Exposure of 100 % LEL When gas reading exceeds 100 % of the lower explosive limit (LEL), the catalytic combustible sensor enters a Lock Alarm state and displays “XXX” in place of the actual reading. WARNING! A catalytic combustible gas reading of "XXX” indicates the atmosphere could be above 100 %LEL or 5.00 % Vol CH4 and an explosion hazard exists. Move away from contaminated area immediately. ALTAIR® 5X PID 26  Description The user can clear the LockAlarm state only by turning the device OFF, and then ON again in a fresh air environment. When catalytic combustible gas reading digits appear, the device is available again for measuring gases. Check national standard values for 100 % LEL. 3.10 Monitoring VOC Gases The device is equipped with a PID sensor that detects a variety of VOC gases. The device displays the gas concentration in parts per million (ppm), µmol/mol or mg/m3 on the Measuring page. WARNING! If an alarm is triggered while using the device, leave the area immediately. Remaining in the area under such circumstances can cause serious personal injury or death. The device has four gas alarms: HIGH Alarm LOW Alarm STEL Alarm TWA Alarm If the gas concentration reaches or exceeds the alarm set point or the STEL or TWA limits, the: alarm message displays and flashes in combination with the corresponding gas concentration backlight turns on alarm sounds (if active) alarm LEDs flash (if active) vibrating alarm triggers (if active) To reset the alarm press the  button. False VOC alarms can occur due to changes in barometric pressure (altitude), humidity or extremechanges in ambient temperature. US It is recommended that a VOC calibration be performed at the temperature, humidity and pressure of use. Be sure that the device is in known fresh air before performing a calibration. For optimal lamp strike, the PID lamp should be started within the normal temperature range. When the device is calibrated in an dry, air conditioned environment and taken to a high temperature and high humidity outdoor environment, a VOC Low or High alarm may be triggered by this sudden change. It is recommended that the PID sensors be cleaned prior to this transition to avoid this situation, or to acclimate the sensor to the outdoor conditions in a known safe area. ALTAIR® 5X PID 27  Description 3.11 Displaying Current Response Factor The current Response Factor (RF) is displayed at device startup along with the PID lamp potential in eV value, sensor range and VOC gas type. During operations, the RF can be displayed through several menus. If the Menu Enable option is On, use the  button on the Main Measuring page to scroll through the menu options and select YES on "Change VOC Gas?". Selecting any gas on this page will display the 8 character gas name, the Response Factor, the Maximum Value of the VOC gas and the current High and Low Alarm values. The Maximum Value is calculated by multiplying the sensor range by the RF. For example, the US Max Value for Hexane is 2000 *4.5 = 9000 ppm. The maximum value cannot exceed 9999 ppm. It is the responsibility of the user to change the VOC Low and High Alarms as appropriate for the applied RF. The selection of the alarm limits must be under the direction of a qual- ified safety professional who has carefully evaluated the specific hazards of the jobsite where it will be used and who is completely familiar with the product and its limitations. A complete list of the 8 character gas name and Response Factors for all VOC gases is contained in chapter 10 "PID Response Factor Table". ALTAIR® 5X PID 28  Operation 4 Operation Device operation is dialog driven from the display with the aid of the three function buttons (→ Fig. 2 "Device view"). For more information, see the flow charts in chapter 11 "Flow Charts". 4.1 Environmental Factors A number of environmental factors may affect the gas sensor readings, including changes in pressure, humidity and temperature. Pressure and humidity changes affect the amount of oxygen actually present in the atmosphere. Pressure Changes If pressure changes rapidly (e.g., stepping through airlock), the oxygen sensor reading may temporarily shift and possibly cause the device to go into alarm. While the percentage of oxygen may remain at or near 20.8 Vol %, the total amount of oxygen present in the atmosphere available for respiration may become a hazard if the overall pressure is reduced by a significant degree. Humidity Changes If humidity changes by any significant degree (e.g., going from a dry, air conditioned environment to outdoor, moisture laden air), oxygen readings can be reduced by up to 0.5 %, due to water vapor in the air displacing oxygen. The oxygen sensor has a special filter to reduce the effects of humidity changes on oxygen readings. This effect will not be noticed immediately, but slowly impacts oxygen readings over several hours. Temperature Changes The sensors have built-in temperature compensation. However, if temperature shifts dramatically, the sensor reading could shift. Combined Humidity and Temperature Changes When the device is calibrated in an dry, air conditioned environment and taken to a high temperature and high humidity outdoor environment, a VOC Low or High alarm may be triggered by this sudden change. It is recommended that the PID sensors be cleaned prior to this transition to avoid this situa- tion, or to acclimate the sensor to the outdoor conditions in a known safe area. 4.2 Turning ON and Fresh Air Setup Device operation is dialog driven from the display with the aid of the three function buttons (→ Fig. 2 "Device view"). For more information, see the flow charts in chapter 11 "Flow Charts". US Turn the device ON with the q button. The device performs a self test: During the self test, the device checks alarm LEDs, audible alarm, vibrating alarm and installed sensors. The device displays: Startup logo Software version, device serial number, company name, department and user names IC / FCC ID Identifier Sampling system safety test During the turn-ON sequence, if a sensor was changed since the previous device operation, the current listing of the installed sensors displays and user interaction is required. The user must accept the new configuration by pressing the  button. ALTAIR® 5X PID 29  Operation If the current sensor configuration is not accepted, the device alarms and is not usable. FCC Identification page Combustible gas type, and installed sensor indication VOC gas type, lamp value, detectable range and Response Factor Alarm setpoints Low Alarm Alarm setpoints High Alarm Alarm setpoints STEL Alarm (if enabled) Alarm setpoints TWA Alarm (if enabled) Settings for calibration cylinder Current date Last calibration date (if enabled) CAL due date. If the calibration due date is enabled, the message "CAL DUE; X DAYS" appears on the device display. X = the number of days until a calibration is due, user selectable for 1 to 180 days. If the number of days until calibration is due reaches 0, an alert occurs and "CAL DUE, NOW" displays. Press the π button to clear the alert Sensor warm-up period Fresh Air Setup option (if enabled). The Main Measure Page will appear. The presence of a ♥ indicator on the display means a sensor is approaching or has reached its end- of-life. See chapter 3.3 "Alarms" for details on the Sensor Life Alarm situation. Refer to flowchart in chapter 11.1 "Basic Operation". Sampling System Safety Test Upon startup, an alarm (visual, audible and vibrating) is triggered and the customer is prompted to block the pumps/sampling system of the device within 30 seconds. When the device detects a pump flow block, it will display a PASS message. The startup sequence will resume. If the device does not detect a pump flow block, it will display an error message. US The device will shut OFF after the customer acknowledges this message by pressing the  button. Check the sampling system if this occurs and contact MSA as needed. Users can check the operation of the sampling system any time during operation by blocking the sampling system to generate a pump alarm. WARNING! Do not use the pump, sample line, or probe unless the pump alarm activates when the flow is blocked. Lack of an alarm is an indication that a sample may not be drawn to the sensors, which could cause inaccurate readings.Failure to follow the above can result in serious personal injury or death.Never let the end of the sampling line touch or go under any liquid surface. If liquid is drawn into the device, read- ings will be inaccurate and device could be damaged. MSA recommends the use of an MSA sample probe containing a special membrane filter, permeable to gas but impermeable to water, to prevent such an occurrence. ALTAIR® 5X PID 30  Operation Fresh Air Setup (FAS) at device Turn-ON The Fresh Air Setup (FAS) is for automatic ZERO adjustment of the device. The FAS has limits. If a hazardous level of gas is present, the device ignores the FAS command and the device alarm activates. The ability to perform an FAS at device turn-ON can be disabled by using MSA Link software. WARNING! Do not perform the Fresh Air Setup unless you are certain you are in fresh, uncontaminated air; other- wise, inaccurate readings can occur which can falsely indicate that a hazardous atmosphere is safe. If you have any doubts as to the quality of the surrounding air, do not use the Fresh Air Setup feature. Do not use the Fresh Air Setup as a substitute for daily calibration checks. The calibration check is required to verify span accuracy. Failure to follow this warning can result in serious personal injury or death. Fig. 7 Fresh Air Setup The device displays a blinking "FRESH AIR SETUP?", prompting the user to perform a Fresh Air Setup: (7) Press the  button to bypass the Fresh Air Setup. The Fresh Air Setup is skipped and the device goes to the Measuring page (Main page). (8) Press the  button to perform the Fresh Air Setup. The device starts the FAS sequence and the FAS screen displays. US A progress bar shows the user how much of the FAS has been completed. At the end of the FAS, the device displays either "FRESH AIR SETUP PASS" or "FRESH AIR SETUP FAIL". If the FAS fails, perform a zero calibration (→ chapter 4.10 "Calibration"). 4.3 Special Consideration for Oxygen Sensor Under the following situations, the oxygen sensor display reading may be suppressed for up to 30 minutes at device turn-ON as a sensor 'cook down' is performed. This could occur if: the oxygen sensor was just installed the battery pack was allowed to be deep-discharged the battery pack was removed from the device. ALTAIR® 5X PID 31  Operation During this time, the oxygen sensor numeric position on the display indicates "PLEASE WAIT". While this message displays, the device cannot respond to a: Fresh Air Setup Calibration Bump Test procedure.

(1) Press the q button to enable or disable the Bluetooth communications device (ON/OFF). (2) Press the  button to to return to the Main Menu or the  button to return to previous page. Back To Main Menu There are three options at this point: the  button Sensor Options menu the  button Previous Setup page in the Instrument Options menu the q button Instrument Options menu 4.6 Bluetooth Operation The Bluetooth communication device must be enabled for any Bluetooth functions to operate. See chapter 4.5 "Device Setup". Compatible Bluetooth host with appropriate software is required for proper operation. Bluetooth Security The Bluetooth connection is encrypted and secured with a unique six digit pin that must be double confirmed on both device and Bluetooth host at the time of pairing. Discovery Mode This device mode is used to enable a Bluetooth host to pair with the device for the first time or if a different Bluetooth host was connected with the device previously. Note that the device will automatically enter discovery mode for five minutes at device turn on if Bluetooth has been enabled. Discovery mode will also be entered for 5 minutes following a disconnection. To manually enter discovery mode: (1) Page down through the menu pages in Measurement Mode using the  button until the Discovery Mode page is displayed. (2) Press the q button to enter discovery mode. The blue led will blink rapidly indicating that the device is in Discovery Mode. Connecting the device to a Bluetooth host for the first time US (1) Ensure that the device is on and in Discovery Mode (2) On the Bluetooth host, locate the Bluetooth device list. Select "A5X-xxxxxxxx" from the list. Both the device and Bluetooth host will display a unique six digit security code to ensure that the correct devices are being paired. (3) After confirming that the six digit codes match, confirm the pairing request on the device by pressing the  button. (4) Confirm on the Bluetooth host as well. Connecting the Device to a Bluetooth Host If this was the last device connected to the Bluetooth host, the Bluetooth host can connect to the device whether or not the device is in discovery mode as long as Bluetooth is enabled. The six digit code confirmation will not be displayed. The device will only recall the last Bluetooth host it was paired with. If connecting to another Bluetooth host, the device must be placed into discovery mode to be detected. ALTAIR® 5X PID 41  Operation Pairing the device to a Bluetooth host This device has an integrated RFID chip to facilitate a faster Bluetooth pairing process with a Bluetooth host that supports a RFID or NFC reader with appropriate software. Simply align the RFID or NFC reader of the Bluetooth host directly over the MSA logo on the front of the device.The device and Blue- tooth host should become paired and connected. Disconnecting the Device from a Bluetooth Host The device does not have a disconnect feature as this would be initiated by the Bluetooth host. Use the Bluetooth host functions to purposefully disconnect the device from the Bluetooth host. Device Configuration over Bluetooth Connection The device has the ability to receive updates to device settings over the Bluetooth connection. The user must successfully pair the device and Bluetooth host confirming that the six digit security code matches both on the device and the Bluetooth host. After a configuration change has been initiated, the user must confirm the request on the device by pressing the  button. Evacuation Alert over Bluetooth Connection The device has the ability to receive an evacuate message over the Bluetooth connection. The user must successfully pair the device and Bluetooth host confirming that the six digit security code matches both on the device and the Bluetooth host. Once connected, an evacuate message sent to the device will send the device into alarm while displaying EVAC on the display. Press the  button to silence the Evacuation alert and confirm the alert was received. Press the  button a second time to reset the Evacuation alert once in a safe area. 4.7 MSA Link Operation Connecting device to PC (1) Switch ON the device and align the Datalink Communication port on the device to the IR inter- face of the PC. (2) Start the MSA Link software on the PC and start the connection by clicking the connect icon. 4.8 Function Tests on the Device Alarm Test (1) Turn ON the device. The user should verify that: alarm LEDs flash horn sounds briefly US vibrating alarm triggers briefly. 4.9 Bump Test WARNING! Perform a Bump Test before each day’s use to verify proper device operation. Failure to perform this test can result in serious personal injury or death. Bump test frequency is often stipulated by national or corporate regulations; however, bump testing before each day’s use is generally the accepted best safety practice and is therefore MSA’s recommendation. This test quickly confirms that the gas sensors are functioning. Perform a full calibration periodically to ensure accuracy and immediately if the device fails the Bump Test. The Bump Test can be performed using the procedure below or automatically using the GALAXY GX2 Test Stand. ALTAIR® 5X PID 42  Operation CSA requires (per 22.2 NO. 152) that combustible sensor sensitivity be tested before each day's use on a known concentration of methane equivalent to 25 to 50 % of full scale concentration. ACCURACY MUST BE WITHIN 0 to +20 % OF ACTUAL. Correct accuracy by performing the calibration procedure described in chapter 4.10 "Calibration". NOTE: The GALAXY GX2 cannot test the Chlorine Dioxide sensor. For this sensor, use this Bump Test procedure and/or manually calibrate as described in chapter 4.10 "Calibration". Equipment See accessory chapter for ordering information for these components. Calibration Check Gas Cylinder(s) See chapter 6.3 "Calibration Specifications" for calibration gas target values and appropriate MSA calibration gas cylinders. Demand Flow Regulator(s) Tubing appropriate for the gases to be tested Kits containing tubing and regulators suitable for reactive and non-reactive gases are available from MSA. Performing a Bump Test (1) While the device is turned ON in a clean, fresh air environment, verify that readings indicate no gas is present. (2) From the normal measure screen press the  button to display “BUMP TEST?”. (3) Verify the gas concentrations displayed match the Calibration Check Gas Cylinder. If they do not, adjust the values through the Calibration Setup menu. Depending on the sensors installed, there could be one to five separate Bump Tests performed, each with a different cylinder, regulator, and tubing used. (4) Attach the demand regulator (supplied in the calibration kit) to the cylinder providing the indi- cated gases. (5) Connect tubing (supplied in the calibration kit) to the regulator. (6) Attach the other end of tubing to the device pump inlet. (7) Press the q button to start the bump test: the progress bar advances the sensors respond to the gas. The message BUMP TEST PASS indicates a successful Bump Test of the sensors. If any sensor fails the Bump Test: US the message BUMP TEST FAIL appears the failed sensor is indicated. If there are more sensors to be Bump Tested, the next sensor displays and the process repeats from Step 4. If there are no more sensors to be Bump Tested, the tubing can be removed from the device pump inlet. ALTAIR® 5X PID 43  Operation After the Bump Test After all installed sensors pass the Bump Test, the √ symbol displays on the MEASURE page. This √ symbol appears on the display in the upper feature bar If any sensor was not bump tested, or fails the Bump Test, the √ symbol does not display. The color display: temporarily shows the √ symbol at each gas reading for successfully bump tested sensors √ symbol is then replaced by the present gas reading. The √ symbol shows for 24 hours after the Bump Test. If a sensor fails the Bump Test, calibrate the device as described in chapter 4.10 "Calibration". 4.10 Calibration The ALTAIR 5X PID can be calibrated either manually using this procedure or automatically using the GALAXY GX2 test stand. Refer to chapter 11.5 "Calibration Options". The use of the demand regulators listed in chapter 9 "Ordering Information" is recommended. If a new sensor has been installed, the battery pack has been depleted or a new battery pack has been installed allow sensors to stabilize for 30 minutes before calibration is performed. WARNING! Special conditions with toxic gases! If the device is to be checked or calibrated for reactive gases, prerequisites are required; otherwise, incorrect calibration would result in incorrect device operation. Reactive toxic gases (e.g., chlorine, ammonia, chlorine dioxide) have the property of diffusing into the rubber and plastic tubes so that the volume of test gas available in the device would no longer be suffi- cient to correctly perform device calibration. When calibrating the device with toxic gases, certain prerequisites are required, otherwise incorrect calibration could result:  A special pressure regulator  Shortest possible connection tubes between the pressure regulator and the device  Connection tubes made from a material that does not absorb the test gases (e.g., PTFE). NOTE: If using normal tubes and pressure regulators, expose them to the required test gas for an US extended time period. Keep these materials dedicated for use with that test gas only; do not use them for other gases. For example, for chlorine, allow the entire contents of a test gas cylinder to flow through the pres- sure regulator and tubes before using to calibrate the device. Mark these materials for use with chlorine only. ALTAIR® 5X PID 44  Operation Zero Calibration Procedure (1) Press the  button for five seconds in Normal Measurement page. ZERO screen displays. To skip the ZERO procedure and move directly to the span calibration proce- dure, push the  button. If no button is pushed for 30 seconds, the device prompts user to perform a SPAN calibration before device returns to the Normal Measurement page. To perform ONLY a Fresh Air Setup at this time, press the q button. The device then performs a Fresh Air Setup as described in chapter 4.2 "Turning ON and Fresh Air Setup". When the Fresh Air Setup is complete, the device returns to the normal Measure screen. (2) Press the  button to confirm the ZERO screen, i. e. to execute zero calibration. The message "SENSOR REFRESH" displays, followed by the message "ZERO CALIBRATION". The "REFRESH" message does not appear if a catalytic combus- tible sensor is not installed. ZERO calibration starts. A progress bar shows the user how much of the calibration has been completed. During the first moments of a ZERO calibration, the combustible sensor reading may be replaced by a moving display of “PLEASE WAIT”. This is normal. After the ZERO calibration is completed the device displays either “ZERO CALIBRATION PASS” or “ZERO CALIBRATION FAIL”. US Only if the device passes the zero calibration the SPAN screen displays. Span Calibration To skip the Span calibration procedure, push the  button. If the SPAN calibration of the combustible sensor is skipped after a successful ZERO cali- bration, the combustible sensor reading may be replaced with a moving display of “PLEASE WAIT” for a few moments. This is normal, and the device is fully operational once a combustible gas reading reappears. ALTAIR® 5X PID 45  Operation If no button is pushed for 30 seconds, span calibration is skipped. Because of the different possible combinations of gases that are possible, skipping a Span calibration could advance the user to the Span calibration of another installed sensor, or back to Measuring mode. When calibrating a 0-2000 ppm PID sensor, use 100 ppm isobutylene balanced in air. Isobutylene calibration gas other than 100 ppm is not allowed due to long term affect on the CO sensor. (1) Connect one end of tubing to the cylinder regulator (supplied in the calibration kit). (2) Connect the other end of the tubing to the pump inlet. (3) Press the  button to calibrate (span) the device. “SPAN CALIBRATION“ flashes SPAN calibration starts. A progress bar shows the user how much of the calibration has already been completed. After the SPAN calibration is completed, the device displays either “SPAN CALIBRATION PASS” or “SPAN CALIBRATION FAIL” The device returns to Measuring mode. US ALTAIR® 5X PID 46  Operation If a sensor is nearing its end-of-life, the "PASS" display is followed by the Sensor Life indicator ♥ display. While the sensor is still fully functional, this warning gives the user time to plan for a replacement sensor to minimize downtime. The ♥ indicator blinks as the device returns to Measure mode. After 15 seconds, the blinking stops, but the ♥ indicator continues to display during ongoing oper- ations as a reminder of a sensor’s pending end-of-life. If a span calibration fails: The Sensor Life Indicator ♥ blinks to show a sensor has reached its end-of-life and should be replaced. The device remains in the Sensor Life alarm condition until the  button is pressed. After the alarm is cleared, the device enters Measure mode and the Sensor Life indicator ♥ blinks during ongoing operations until the sensor is replaced and/or successfully calibrated. Span calibration can fail for reasons other than a sensor at the end of its life. If a span calibration failure occurs, verify items such as: sufficient gas remaining in the calibration cylinder gas expiration date integrity of calibration tubing/fittings, etc. Reattempt the span calibration before replacing the sensor. Finishing Successful Calibration (1) Remove the calibration tube from pump inlet. The calibration procedure adjusts the span value for any sensor that passes the calibration test. Sensors that fail calibration are left unchanged. On the color display, each successfully calibrated sensor temporarily shows a √ symbol at its gas reading. These √ symbols remain visible for a few moments and are then replaced by the present gas reading. Since residual gas may be present, the device may briefly go into an exposure alarm after the calibra- tion sequence is completed. (2) Press the  button to reset the alarm as necessary. Following a PID sensor calibration, VOC gas readings may be slightly elevated (< 5 ppm) for several US minutes. This is normal behavior as the isobutylene is purged from the device. A √ symbol displays on the MEASURE page.This √ symbol appears on the: color display in the upper feature bar The √ symbol displays for 24 hours after the calibration and then turns off. If the horn alarm is turned OFF, the calibration √ symbol does not appear on the color display. ALTAIR® 5X PID 47  Operation Calibration with an Automated Test System The device can be calibrated using the GALAXY GX2 Automated Test System - contact MSA for a list of compatible gases and concentrations. Similar to the successful (manual) calibration described in chapter "Finishing Successful Calibration", a √ symbol displays on the MEASURE page after successful GALAXY GX2 calibration. This √ symbol appears on the display in the upper feature bar. The √ symbol displays for 24 hours after the calibration and then turns off. If the horn alarm is turned OFF, the calibration √ symbol does not appear on the color display. 4.11 Time of Day Testing This feature permits the device to be automatically calibrated on a user-defined interval. The most common use of this feature allows the user to configure the ALTAIR 5X PID and the GALAXY GX2 System to automatically calibrate a device prior to the start of work-shift. See the GALAXY GX2 Oper- ating Manual ("Automated Testing Features" section) for a complete description of how to configure the GALAXY GX2 for this mode. On ALTAIR 5X PID devices, the following settings must be configured using either MSA Link or the GALAXY GX2 → Instrument Setup page: For automated calibration testing, Calibration Due must be enabled and a non-zero Calibration Interval must be entered for automatic calibration testing For automated bump testing, Bump Due must be enabled and a non-zero Bump Interval must be entered for automatic bump testing Carefully follow all GALAXY GX2 set-up directions as described in the GALAXY GX2 Operating Manual for proper setup. 4.12 Device Shutdown For device shutdown press and hold the q button. US Fig. 11 Shutdown The device displays a blinking "HOLD BUTTON FOR SHUTDOWN" and a progress bar shows the user how much longer to hold the button to complete the shutdown.

INVALID CONFIGURA- Sensor(s) installed in incorrect Install sensors as shown in Figure Fig. 13 location. "Possible positions for sensor replacement". US TION 5.2 Verifying Pump Operation Users can check operation of the sampling system any time during operation by blocking the sampling system to generate a pump alarm. When the pump inlet, sample line or probe is blocked, the pump alarm must activate. Once gas readings are displayed, plug the free end of the sampling line or probe. The pump motor shuts down and an alarm sounds. PUMP ERROR will flash on the display. (1) Press the  button to reset the alarm and restart the pump. If the alarm does not activate: Check the sample line and probe for leaks. Once leak is fixed, recheck pump alarm by blocking the flow. (2) Press the  button to reset the alarm and restart the pump. ALTAIR® 5X PID 50  Maintenance WARNING! Do not use the device, sample line, or probe unless the pump alarm activates when the flow is blocked. Lack of an alarm is an indication that a sample may not be drawn to the sensors, which could cause inaccurate readings. If a sample line or probe is installed and the pump alarm does not activate, remove the line or probe and repeat the test. This will provide information on where the blockage is located.Failure to follow the above can result in serious personal injury or death.Never let the end of the sampling line touch or go under any liquid surface. If liquid is drawn into the device, readings will be inaccurate and device could be damaged. We recommend the use of an MSA sample probe containing a special membrane filter, permeable to gas but impermeable to water, to prevent such an occurrence.

Calibration is required after a sensor is installed; otherwise, the device will not perform as expected and persons relying on this product for their safety could sustain serious personal injury or death. 5.5 Replacing the Pump Filter (1) Turn OFF the device. (2) Unscrew the two captive screws from the clear filter cover on the back of the device to access the filter. (3) Carefully lift out the O-ring and the filter disk(s). (4) Use both the paper-like filter and the fibrous dust filter (the thicker disk) as supplied in the Main- tenance Kit if the device is NOT configured to use a reactive toxic gas sensor (does not have a Cl2, ClO2, or NH3 sensor). Use ONLY the paper filter supplied in the Reactive Gas Maintenance Kit if the device IS config- ured to use a reactive toxic gas sensor (Cl2, ClO2, or NH3). (5) Place the new paper-like filter into the recess in the back of the device. If it is to be used, place the fibrous dust filter into the clear filter cover. WARNING! US Use of the fibrous dust filter or the incorrect paper filter for the measurement of reactive gases could cause erroneous readings. (6) Replace the O-ring in the recess. (7) Re-install the clear filter cover on the back of the device. 5.6 Cleaning the Device Exterior Clean the exterior of the device regularly using only a damp cloth. Do not use cleaning agents as many contain silicones which will damage the combustible sensor. 5.7 Storage When not in use, store the device in a safe, dry place between 18 °C (65 °F) and 30 °C (86 °F).
