7. Performing A Bump Test
RAE Systems recommends that a bump test be performed on all portable instruments
prior to each day’s use. A bump test is defined as a brief exposure of the monitor to the
test gas to make sure that sensor respond to gas and alarms are functional and enabled.

The monitor must be calibrated if it does not pass a bump test, or at least once
every 180 days, depending on use and sensor exposure to poisons and
contaminants.

Calibration intervals and bump test procedures may vary due to national
legislation.
1. Connect calibration gas cylinders that match the gas settings configured on the Cradle
(as specified for Bottles 15 and 16 under Gas Config 8; see Section 13.1).
2. Insert an instrument in the AutoRAE 2 Cradle (as described in Section 6.4) and wait
for it to warm up (as described in Section 6.5).
3. When the instrument is warmed up (both LEDs are glowing green), press “Bump” to
initiate a bump test. The Cradle produces a beep to signal the start of a bump test.
4. The Bump LED flashes green when a bump test is under way. The Cal LED stays
dark.
5. If the instrument passes a bump test, the Bump LED will turn solid green.
Note: See page 32 for an explanation of the LED indications that tell you which
operations are underway and which LED indications tell you of errors during a bump test.
Note:
In its standard configuration, if the instrument does not successfully pass a bump
test, the AutoRAE 2 Cradle automatically initiates a full calibration.
