Calibrating GX-2012s and Gas Tracers • 200
If you are calibrating a 0 - 10000 ppm range Gas Tracer, the Gas Cylinder
Confirmation Screen will appear as shown below. Even though there are no
other sensors installed in the instrument, GAS 2 will still be used to calibrate
the ppm sensor. The ppm sensor will be deselected in this screen and cannot
be selected.

When all of the desired channels are selected, click OK. If you don’t want to
proceed, click Cancel to abort the calibration.

You will then be asked to confirm the auto calibration values and the
instruments that the calibration cylinder will be used for. Be sure that the auto
calibration values match the values listed on the calibration cylinder. The serial
number and gas combination of all selected instruments will appear
sequentially beneath the gas cylinder concentrations. If you are calibrating
standard GX-2012s (catalytic LEL, O
2
, H
2
S, and CO) and standard Gas
Tracers (catalytic LEL, ppm combustible, O
2
, and CO), the screen will appear
as shown below. The ppm sensor will be calibrated first with GAS 2 and then
the remaining sensors will be calibrated with GAS 1. The GAS 2 selection box
is deselected by default. You must select the GAS 2 box if you wish to calibrate
the ppm combustible sensor. If you do not wish to calibrate the ppm
