Study Notes
Password Setup and Programming Mode
- The default password is 0000; users can change it by increasing numbers (0-9) using [Y/+].
- Navigate between digits using [N/-]; press [MODE] to finish inputting the password.
- The password screen appears only after turning the device on in Basic Mode.
- Entering Programming Mode allows access to various settings without needing to re-enter the password until the device is turned off.
- The Calibration menu is automatically highlighted upon entering Programming Mode.
Menu Structure
- In Programming Mode, menu options include:
- Calibration
- Measurement
- Alarms
- Datalog
- Wireless (available on wireless instruments)
- Monitor
Calibration Options
- Fresh Air calibration sets the zero point for sensors, specifically aligning the oxygen sensor to ambient air levels (~20.9%).
- Bump tests and span calibrations can be performed for multiple sensors by selecting appropriate gas concentration values.
Calibration and Bump Test Indicators
- An icon indicates if calibration is required for sensors, triggered by:
- Changes in lamp type.
- Replacement of overdue calibration sensors.
- Exceeding the calibration time period.
- Changes in calibration gas types.
- A bump test is necessary if:
- The defined time between tests is exceeded.
- The sensor has previously failed a bump test.
Modes of Operation
- Hygiene Operation Mode: Continuous monitoring of the environment.
- Search Operation Mode: Monitoring occurs only when specifically initiated.
- Basic User Mode: Includes restrictions and password protection for safety.
- Advanced User Mode: No access restrictions; ideal for typical monitoring tasks.
Accessing Programming Mode
- Enter Programming Mode in Advanced Mode by holding [MODE] and [N/-], no password needed.
- In Basic Mode, access Programming Mode by holding [MODE] and [N/-] until reaching the Password screen.
Wireless Status Indicators
- Wireless status can indicate if the radio is on or off.
- Datalogging status shows when logging is active; blank when inactive.
- Wireless strength is represented by a bar graph ranging from 0 to 5 bars.
- Battery status is displayed with three segments indicating the charge level.
- Pump status is visible only on pump-equipped models.
Sensor Calibration and Testing
- Alerts when a sensor is due for calibration or a bump test.
- A tick mark signals that all sensors are tested and calibrated within configured intervals.
MultiRAE Keys and Interface
- The MultiRAE features three keys: [Y/+], [MODE], [N/-].
- Keys can activate display backlighting; one key press turns it on, another performs the function.
- Display orientation automatically flips when the device is inverted for better readability.
Battery Options
- Alkaline battery adapter allows the use of four AA batteries (Duracell MN1500 recommended) for approximately 8 hours of operation.
- Alkaline adapter disables vibration alarms and must be installed correctly according to polarity markings.
- Proper disposal procedures for old batteries are emphasized.
Powering the MultiRAE
- To turn on, press and hold [MODE] until a beep sounds; a sequence of screens will follow displaying crucial information.
- It is possible to enable fast startup to reduce the number of screens displayed during startup.
Calibration Procedures
- Fresh air calibration can be done across multiple sensors using dry air or a calibration adapter.
- Span calibration can be performed simultaneously on multiple sensors; MultiRAE intelligently prompts for different gas calibrations.
- Individual sensor zero calibration can be initiated but should not be done for CO2 and VOC sensors in ambient air due to their natural presence.
Policy Enforcement Features
- Policy enforcement can require regular bump testing and calibration before normal use.
- Non-compliance with policy settings may restrict instrument operation.
- Changes to policy enforcement settings can be made through ProRAE Studio II software.
Calibration Best Practices
- CO2 sensor zero calibration must be performed in 100% nitrogen gas only.
- Parts-per-billion PID sensor for VOCs should be zeroed with ambient air using a filtering method, not fresh air.
- The MultiRAE should undergo a clean air zero calibration for accurate sensor readings.
Additional Calibration Information
- Three-point calibration is available for enhanced linearity with extended-range and ppb PID sensors but is disabled by default.
- Manual calibration displays readings in the units of the calibration gas, not the measurement gas.
