WARNINGS Read Before Operating MultiRAE Lite Diffusion QuickStart Guide User Interface The MultiRAE User’s Guide must be carefully read by all individuals who have or will have the responsibility of using, maintaining, or servicing this product. The product will perform as designed only if it is used, maintained, and serviced in accordance with the manufacturer’s instructions. CAUTION! Never operate the monitor when the rear cover is removed. Remove rear cover, sensors, and/or battery only in an area known to be non-hazardous. Never use the instrument with the calibration adapter installed, as this can cause distorted readings, a potential safety threat. For Sales & Service Contact 1-800-833-7958 www.geotechenv.com 2. Charging The MultiRAE MultiRAE With the instrument turned off, press and hold the [MODE] key until the audible alarm stops, and then release. During startup, the battery, buzzer, vibration alarm, and LEDs are tested, and then the MultiRAE performs self-testing of its functions. When the main measurement screen appears, the MultiRAE is ready for calibration or use. Gas inlets [MODE] key [Y/+] key Alarm Buzzers Charging and Communication Contacts LEDs 3. When the countdown ends and the screen displays “Unit Off,” release your finger from the [MODE] key. The MultiRAE is now off. 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. Testing The Alarm Note: If Fast Startup is enabled on the instrument, fewer screens are shown during startup, compared to Normal Startup sequence. 4. Rear Press and hold [MODE]. A 5-second countdown to shutoff begins. You must continue pressing on the key for the entire shutoff process. If you remove your finger from the key during the countdown, the shutoff operation is canceled and the MultiRAE continues normal operation. Charger Charging status LED LEDs Turning The MultiRAE Off Turning The MultiRAE On Always fully charge the battery before use. Contacts on the bottom of the MultiRAE meet the Travel Charger’s or Charging Cradle’s contact pins, transferring power. Make sure the charger and MultiRAE are firmly attached. Then connect the AC Adapter’s barrel plug to the charger, and plug its transformer into an AC outlet. While charging, the LED on the cradle glows red. When the battery is fully charged, the LED glows green.

The flippable LCD displays information such as threat real-time readings and measurement units, monitored threat, alarm type (when in alarm, including cal. overdue), battery status, datalog (if on), and radio and connection quality (if available). 5. Under normal-operation mode and non-alarm conditions, the buzzer, vibration alarm, LED, and backlight can be tested anytime by pressing [Y/+] once. If any alarm does not respond, check the Alarm Settings in Programming Mode to make sure all alarms are enabled. If any alarms are enabled but are not functional, do not use the instrument. 6. Calibration Zero & Fresh Air Calibration The MultiRAE can be automatically bump tested and calibrated using the AutoRAE 2 Test and Calibration System (refer to its User’s Guide for instructions). Manually calibrate using a fixed-flow regulator (flow rate between 0.5 and 1.0 liters per minute) and the supplied special calibration adapter that covers the gas inlet: The MultiRAE should be zero-calibrated in clean air with 20.9% oxygen or with a cylinder of clean zero air. In Programming Mode, select “Fresh Air.” Then: Press [Y/+] to start a Fresh Air calibration for the listed sensors. All are fresh-air calibrated at once. To individually zero calibrate sensors: 1. Select “Single Sensor Zero” and select a sensor. 2. Press [Y/+] to select a sensor to zero calibrate. 3. Start the flow of the zero gas, and press [Y/+]. 4. The screen says, “Zeroing” and counts down. 5. When done, it says, “Zero Calibration Passed” (the reading should be 0.0 ppm or very close to it for toxic gas sensors, and 20.9% Vol. for an oxygen sensor). 6. Shut off the flow of zero air (if used) and remove the calibration adapter. Note: If your MultiRAE is equipped with a CO2 sensor, it must be zero calibrated using 100% Nitrogen (N2), or 8. isobutylene, instead of fresh air or zero air. 1. To begin calibration, connect the zero air or calibration gas cylinder, flow regulator, and calibration adapter to the MultiRAE. 2. Enter Programming Mode by pressing and holding [MODE] and [Y/+] simultaneously until the password screen appears. 3. Input the 4-digit password. (The default password is “0000.” If you do not know the password, select “Done.”) Then follow the instructions for individual or multiple zero and span calibration. Important! After a bump test or calibration, remove the 7. calibration adapter to ensure correct readings. Bump (Functional) Testing RAE Systems recommends periodic bump testing to confirm that the sensors and alarms are functional. Test each sensor with an appropriate test gas in a concentration not less than the sensor’s low alarm setting. To pass, each sensor should go at least to a low alarm. With the MultiRAE in Normal Mode: 1. Connect the calibration gas cylinder, flow regulator, and calibration adapter to the MultiRAE and start the gas flow. 2. Make sure the unit goes into at least a low alarm for each of the tested sensors and that the buzzer produces at least two beeps per second, the LED lights flash on and off, and the vibration alarm functions. The display backlight should illuminate and an alarm message should be shown in the display. 3. Turn off the gas flow. 10. 4. Remove the calibration adapter. Span Calibration In Programming Mode, and with “Multi Sensor Span” or “Single Sensor Span” highlighted: 1. Press [Y/+]. The screen displays the sensor(s) to be calibrated. · Multi: The list is shown. · Single: Select a sensor and press [Y/+] 2. Attach the calibration adapter, and connect the calibration gas cylinder’s flow regulator to the MultiRAE, and start the gas flow. 3. Press [Y/+] to start calibration. 4. Upon completion, a pass/fail calibration result appears and the readings are shown (they should be within ±10% of the span gas value). 5. Turn off the gas and remove the calibration adapter. 9. Basic Menu Navigation In Hygiene Mode Pressing [MODE] repeatedly allows you to step through the screens as shown here. Note: The gray box indicates the datalog functions when datalogging is in Manual mode. When datalogging is in Automatic mode, this screen does not appear. Refer to the User’s Guide for information on selecting Automatic, Manual, or Snapshot datalogging. 11. P/N: M01-4017-000 Rev A 201106
