    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.
    • 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.
