Appendix C: Using the GX-6000 in Leak Check Mode
Overview
This chapter explains how to operate the GX-6000 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 GX-6000 is in Leak Check Mode,
only the catalytic combustible sensor and potentially the CO sensor, depending on the
setting of the
CO DISPLAY
parameter in Maintenance Mode, will be active.
NOTE:
If the
CO DISPLAY
parameter in Maintenance Mode is set to
ON
, the CO
channel will appear in Leak Check Mode. If the
CO DISPLAY
parameter is set
to
OFF
(factory setting), the CO channel will not appear in Leak Check Mode.
All screens in this section do not show the CO channel. If your instrument’s
CO
DISPLAY
is set to
ON
, your screens may appear different.
If a GX-6000 is intended for tracking down leaks, it is shipped with Leak Check Mode or
both Leak Check Mode and Bar Hole Mode enabled so that the operator must choose
which operational mode to use when the unit is turned on (see “Updating the Leak Check/
Bar Hole Mode Setting (L./B. MODE)” on page 152).
