Performing a Fresh Air Adjustment
Before using the Gas Tracer for leak checking, it is recommended to
set the fresh air reading by performing a fresh air adjustment. This
will set the combustible gas channel to zero.
1. Find a fresh-air environment. This is an environment free of toxic
or combustible gases and of normal oxygen content (20.9%).
2. Turn on the unit as described above in “Turning On the Gas Tracer”
on page 16.
3. Press and hold the AIR▲ button. The display will prompt you to
hold the AIR▲ button.
4. Continue to hold the AIR▲ button until the display prompts you to
release the AIR▲ button. The Gas Tracer will set the fresh air
reading for the combustible channel. Once the fresh air adjustment
has finished, start up is complete and the unit is ready for leak
testing.
5. If you would like to calibrate the Gas Tracer while in Leak Check
Mode, follow the same instructions described in “Calibration
Mode” on page 35.
