MultiRAE Features: Internal Pump� Makes remote sampling easy� Sample draw over 100 feet!� Liquid water trap for added protection� Pump stall feature: when moisture is
detected or when pump is blocked the pump will shut off, protecting the MultiRAE from potential damage
� ~150cc/min at Low flow, ~250cc/min at High flow
� Only use Teflon tubing when PID is installed
![Page 9: Multirae user training_310a](https://reader034.fdocuments.net/reader034/viewer/2022042701/55a3ff831a28ab68298b4683/html5/thumbnails/9.jpg)
MultiRAE Features: External Prefilter� Always use the prefilter� Replace when it looks very dirty� Replace when MultiRAE is in pump alarm
with the filter on and you can clear the pump alarm with the filter off.
You wouldn’t leave your house without putting on your pants so
don’t use the MultiRAE without its external filter!

� Unplug MultiRAE from charger� Hold “MODE” Key to turn on� Alarm will beep once� Watch display screen for messages such as:
• Sensors installed & their warranty expiration
• Alarm limits• Last calibration date• User/Alarm/Datalog modes
� Warm-up will take approximately 90 seconds

MultiRAE: Sensor Replacement� Make sure that sensors/dummy sensors fill
all places to prevent gas leakage� Replace gas plate and tighten screws� Replace battery� Turn on MultiRAE� After warm up period, block pump inlet
• If pump does not stall, inspect pump hose connections and reconnect if necessary
• If pump stalls, replace MultiRAE cover and calibrate monitor
![Page 70: Multirae user training_310a](https://reader034.fdocuments.net/reader034/viewer/2022042701/55a3ff831a28ab68298b4683/html5/thumbnails/70.jpg)
MultiRAE: When to Clean PID Sensor� PID works but creeps up to 10+ ppm even
in clean air after “Fresh Air Calibration”� Rapid movements of MultiRAE sends PID
into alarm due to dirt movement in sensor� PID responds to moisture� Always check for clean inlet filters and
tubing prior to cleaning PID
![Page 71: Multirae user training_310a](https://reader034.fdocuments.net/reader034/viewer/2022042701/55a3ff831a28ab68298b4683/html5/thumbnails/71.jpg)
MultiRAE: PID Sensor Clean/Replace� Open MultiRAE� Unplug battery� Remove 4 screws holding gas plate� Carefully lay gas plate back into battery
compartment without disconnecting hoses to pump
� Remove silver shielding cap from PID sensor
� Gently pull out PID sensor (white Teflon)
![Page 72: Multirae user training_310a](https://reader034.fdocuments.net/reader034/viewer/2022042701/55a3ff831a28ab68298b4683/html5/thumbnails/72.jpg)
MultiRAE: PID Sensor Clean/Replace� Dip entire PID sensor into lamp cleaning
solution for at least 3 minutes (an ultrasonic cleaner is recommended, but a shot glass is the perfect sized container)
� Dry sensor thoroughly (warm air will speed up this process) overnight is best
![Page 73: Multirae user training_310a](https://reader034.fdocuments.net/reader034/viewer/2022042701/55a3ff831a28ab68298b4683/html5/thumbnails/73.jpg)
MultiRAE: PID Lamp Clean/Replace� To remove lamp from MultiRAE, grasp
lamp by sides and pull out. Try not to touch the flat lamp surface.
� If lamp works, use a cotton swab to clean the flat lamp surface with cleaning solution
� Replace lamp, DO NOT TOUCH FLAT!� Install battery and turn on MultiRAE
• If after warm-up, lamp lights proceed with reassembly
• If lamp does not light, replace lamp
![Page 74: Multirae user training_310a](https://reader034.fdocuments.net/reader034/viewer/2022042701/55a3ff831a28ab68298b4683/html5/thumbnails/74.jpg)
MultiRAE: PID Lamp Clean/Replace� Replace white Teflon PID sensor� Replace silver PID shielding cap� Make sure that all sensors (in TOX1 and
TOX2 spots) are in place to prevent gas leakage
� Replace gas plate and tighten screws� Replace battery� Turn on MultiRAE

MultiRAE: PID Lamp Clean/Replace� After warm up period, block pump inlet
• If pump does not stall, inspect pump hose connections and reconnect if necessary
• If pump stalls, replace MultiRAE cover and calibrate monitor, do not overtighten screws

MultiRAE: Gas Plate Cleaning� If PID still creeps after cleaning PID sensor
it is recommended to clean the gas plate� Follow instructions to remove pump from
gas plate� Immerse gas plate in lamp cleaning
solution without pump attached (a ultrasonic cleaner will speed cleaning)
� Dry gas plate with warm air� Follow instructions for pump replacement
