Bump Testing & Calibrating QRAE II (Diffusion Version)
RAE Systems recommends that a bump test be performed on the QRAEII before the
monitor is used or being put into service. A bump test is defined as a brief exposure
of the monitor to the calibration gas and the sensors to show response and trigger the
lowest alarm set point for each sensor.
•
The QRAEII 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.
Note: Bump test and calibration can also be performed by using the RAE Systems
AutoRAE Lite For QRAE II docking station.
