11. If the Gas Tracer experiences a sensor failure during start up, a screen
indicating which sensor failed displays. In the example below, the CO sensor
has failed.
If you wish to continue, press and release the RESET SILENCE button to
acknowledge the failure. The gas reading for the failed sensor will be replaced
by “---”. Replace the failed sensor as soon as possible.
12. The Gas Tracer is now operating in Normal Mode and monitoring for gas in
Measuring Mode. The Normal Operation Screen appears.
The concentrations of the target gases are displayed along with the time and
battery charge level. The heart symbol displayed just to the left of the battery
charge level flashes while the instrument is functioning properly. If it
disappears or is steadily on, the unit is experiencing a microprocessor error.
The fan symbol just to the left of the heart symbol spins while the pump is
operating.
Turning On the Gas Tracer in Normal Mode With All Modes Active
If the L./B. MODE item in Maintenance Mode is set to LC, bH, or LC bH (see
“Updating the Leak Check/Bar Hole Mode Setting” on page 154), then the user
must select Normal Mode during the start up sequence to operate in Normal
Mode. The standard factory setting is LC. See “Chapter 4: Using the Gas Tracer in
Bar Hole Mode” on page 87 for a description of Bar Hole Mode or “Chapter 5:
Using the Gas Tracer in Leak Check Mode” on page 96 for a description of Leak
Check Mode.
The following description of the Gas Tracer start up sequence assumes that the
following menu items in Maintenance Mode are turned on: LNCH BRK, ID DISP,
CL RMNDR
, and BP RMNDR. If any of these items is turned off, then the
corresponding screen will not appear. It also assumes that L./B. MODE is set to
LC bH. If L./B. MODE is set to LC, the Bar Hole Mode Select Screen will not
appear. If L./B. MODE is set to bH, the Leak Check Mode Select Screen will not
appear.
