Bump Testing GX-2012s and Gas Tracers • 184
If you are bump testing any instruments that include a %volume sensor, the
screen will appear as shown below and will indicate a gas cylinder change is
needed. The ppm sensor will be bump tested first with GAS 2. The standard
sensors will then be bump tested using GAS 1. The %volume sensor will then
be bump tested with GAS 2. The user must change the GAS 2 cylinder before
the %volume sensor can be bump tested. The GAS 2 selection boxes are
deselected by default. You must select the GAS 2 boxes if you wish to bump
test the ppm combustible sensor and/or the %volume sensor. If you do not
wish to bump test the ppm combustible sensor or the %volume sensor, leave
the appropriate GAS 2 box deselected. Be sure that the ppm calibration
cylinder is connected to the GAS 2 fitting with a 6 inch humidifier at the start of
the bump test.
