Bump Testing And Calibration
RAE Systems recommends that a bump test be conducted periodically on the MicroRAE. 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 MicroRAE multi-gas detector 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.
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.
