IMPORTANT!
If one or more sensors fails a bump test, be sure to calibrate those sensors.
7. The bump test is now complete. Press Exit to return to the main measurement screen.
8. Now perform a manual alarms test, as described in section See " Calibration and Testing"
on page 121 for more information..
If all the alarms and all sensors have passed and no sensor is due for a calibration, the
instrument is now ready for use.
Note: When a manual bump test is performed, the readings shown are in the equivalent units of
the calibration gas, and not the measurement gas (if different).
Testing the Gamma Radiation Sensor
The gamma radiation sensor does not require user calibration. You can check it by placing a
check-source on the rear of the MultiRAE equipped with a gamma sensor to check the readings
(Lantern Mantle PN: 029-5900-000). A raised dot on the rubber boot marks where the sensor is
located inside the instrument.
