10. The Battery Level and Alarm Pattern Screen appears next.
AL -- H indicates latching (hold) alarms and AL -- A indicates self-resetting
(automatic) alarms. The number shown indicates the voltage of the batteries. If
the unit is powered by alkaline (dry cell) batteries, a “D” will appear before
the “V” in the lower right corner.
11. The display then indicates the full scale values for all channels.
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.
