6. You can abort the calibration at any time during the countdown
by pressing [N/-].
7. If the calibration is not aborted, the display shows reading and
then tells you whether the bump test passed or failed. If the bump
test failed, then it automatically advances to the Calibration
screen.
A bump test can be performed either manually or using the AutoRAE
2 Automatic Test and Calibration System. When a bump test is done
manually, the instrument makes a pass/fail decision based on sensor
performance, but the user still has the responsibility to make sure all
the alarms are enabled and functional.
Note: Bump testing and calibration can be performed using an
AutoRAE 2 Automatic Test & Calibration System. An AutoRAE 2
bump test takes care of both the sensor and alarm tests. Consult the
AutoRAE 2 User’s guide for details.
The same gas is used for a bump test as for calibration. The
instrument must be connected to a cylinder of calibration gas with
supplied tubing.
IMPORTANT!
If the instrument does not pass a bump test, perform a full calibration.
If calibration also fails, the PID sensor or lamp may require cleaning
or replacement. If the instrument repeatedly fails to calibrate, turn it
off and refer it for servicing.
Important!
Anytime a bump test fails, you should perform a full calibration of the
instrument.
