Chapter 14 - Bump Test - Honeywell MiniRAE 3000+ User Manual

CHAPTER
14
Honeywell recommends that a bump test be conducted prior to each day's use. The purpose of
a bump test is to ensure that the instrument's sensors respond to gas and all the alarms are
enabled and functional.
The 3GPID must be calibrated if it does not pass a bump test when a new sensor is installed,
l
after sensor maintenance has been performed, or at least once every 180 days, depending
on use and sensor exposure to poisons and contaminants.
Calibration and bump test intervals and procedures may vary due to national legislation and
l
company policy.
To perform a bump test (functional challenge), follow these steps:
1. Select "Bump."
2. Install the calibration adapter and connect it to a source of calibration gas.
3. Verify that the displayed calibration value meets the concentration specified on the gas
cylinder.
4. Press [Y/+] to start the bump test.
5. Start the flow of calibration gas.
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.
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.
