199 • Calibrating GX-2012s and Gas Tracers
7.
You will be asked to confirm which instrument channels will use GAS 1 for the
calibration. The gas concentration shown next to each channel is the auto
calibration value for that channel. If it does not match the gas concentration in
the cylinder(s), change the auto calibration value for that channel. See “Sensor
Tab” on page 165 for instructions. If you are calibrating standard GX-2012s
and standard Gas Tracers, leave the first channel (the ppm sensor) deselected
and select all other channels. If any of the instruments you are testing includes
a %volume sensor, leave the first and last channels (the ppm and %volume
sensors) deselected and select all other channels.
