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 26).

mode will result in shorter battery life than specified in
“Specifications” on page 3.
