GX4 GAS MONITOR

SENSOR CHECK

The gas sensor cartridges come pre-calibrated, but they should be checked regularly to ensure
they are still calibrated within government regulations.
Select "Menu"  "Sensors"  "Check Sensors", then follow the prompts on the display menu to
run a Sensor Check on each cartridge.
You will need:

Zero Air Bottle (08-460) containing 20.9% Oxygen in Nitrogen
 Control Air Bottle(s) specific to the gas of the cartridge(s) being checked
 Calibration Kit (08-450) to connect the bottles to the GX4
IMPORTANT: Alarms will be disabled. You must confirm the monitor is not in use. Always wear
P.P.E., such as face and respiratory protection, and work in a well ventilated area when working
with compressed air and hazardous gases.
Calibration Gas should be supplied between 1 and 4slpm or via a pressure regulator. Using the
08-461 and 08-451, up to 40 calibration checks can be performed.
FIGURE 9.1
Connect the test air bottles to the air inlet.
The unit will confirm if the cartridge(s) are still in calibration or not. If the cartridge(s) pass, you
may proceed to checking the next cartridge(s) or using the monitor. If the cartridge(s) are no
longer in calibration, replace the cartridge(s) with a new one(s).
Sensor Checks are recorded into the Logs and Certificates can be generated using the web
interface.
