12.If the Gas Tracer experiences a sensor failure during start up, a
screen indicating which sensor failed displays. In the example
below, the combustible gas ppm sensor has failed.
If the ppm sensor fails, it is not possible to enter Leak Check Mode.
Press and release the RESET SILENCE button twice to
acknowledge the failure and return to the Mode Select Screen.
Replace the failed sensor as soon as possible.
If the oxygen or CO sensor is installed and fails, press and release
the RESET SILENCE button to acknowledge the failure and
continue to Leak Check Mode.
If an LEL or vol% sensor is installed and fails, no indication will be
given and the unit will enter Leak Check Mode.
13.The Gas Tracer is now operating in Leak Check Mode.
The combustible gas reading is displayed along with the battery
charge level.
Performing a Fresh Air Adjustment, Leak Check Mode
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,
Leak Check Mode” on page 101.
