Assembling the Calibration Kit

WARNING: Calibrate the Model GX-2001 in a non-hazardous

environment.

1. Attach the adapter plate to the unit. It snaps onto the sensor area.

2. Attach the calibration tubing to the adapter plate, then attach the

opposite end of the tubing to the regulator.

NOTE: Do not attach the regulator to the gas cylinder at this time.

If you are going to calibrate the Model GX-2001 for all the target
gasses at one time, it is recommend that you start with the oxygen
sensor first followed by the H

S, CO, and HC sensors in that order.

The reason for this calibration sequence is that while the Model GX-
2001 is in Calibration Mode, you will only be able to toggle through
the target gasses one time, using the MODE/POWER button,
before the unit goes into its start-up sequence.

If you want to go back to a target gas, you will need to turn off the
Model GX-2001 before putting the unit back into Calibration Mode.
