Gas Tracer Operator’s Manual, CSA Version
Chapter 5: Using the Gas Tracer in Leak Check Mode
Overview
This chapter explains how to operate the Gas Tracer in Leak Check Mode. Leak
Check Mode is used to pinpoint small leaks of combustible gas from valves,
flanges, connections, and other potential leak points. When the Gas Tracer is in
Leak Check Mode, only the combustible channel is displayed.
If a Gas Tracer is intended for leak check testing, it is shipped with Leak Check
Mode enabled so that the operator must choose which operational mode to use
when the unit is turned on (see “Turning On the Gas Tracer in Normal Mode With
All Modes Active” on page 30).
Start Up, Leak Check Mode
This section explains how to start up the Gas Tracer in Leak Check Mode and get
it ready for operation.
NOTE:
The battery drain is higher in Leak Check Mode than in Normal Mode
or Bar Hole Mode. Extended operation in this mode will result in
shorter battery life than specified in “Specifications” on page 10.
Turning On the Gas Tracer, Leak Check Mode
WARNING:
If an oxygen sensor is installed, it will not be active while the Gas
Tracer is in 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 either of these items is turned off, then the
corresponding screen will not appear.
NOTE:
In order for LEAK CHECK MODE to appear as a selection in the Mode
Select Screen in Step 3 below, the L./B. MODE item in Maintenance
Mode must be set to LC or LC bH. The factory setting is LC.
1. Connect the tapered rubber nozzle to the inlet fitting.
2. If a sample hose is used, connect the sample hose to the Gas Tracer’s quick
connect inlet fitting.
NOTE:
If a probe is used when using the Gas Tracer in Leak Check Mode, use
the standard probe, not the bar hole probe.
