LEAK SEARCH MODE
OPTIONAL FEATURE
PURPOSE:
Combustible gas leak investigations and surveys, where the PPM scale is needed
LEAK SEARCH mode is an optional feature in the
SENSIT GOLD G3 i
ntended for use in
combustible gas leak investigations or surveys that require the PPM scale. It gives the operator a
separate screen from the normal working display that shows only the combustible gas reading.
This reading starts in the PPM scale, which allows for a higher resolution to be shown on-screen
than would normally be available. The instrument will read in 1PPM increments up to 5000PPM,
auto range to %LEL and then to %VOL.
The instrument has a preset alarm of 50PPM (if not otherwise specified) while in leak search
mode (factory adjustable). This is an additional and separate alarm from the standard set of
alarms available on the working display.
See the Alarms section for more information�

by blocking the inlet(s) of the probe. Within 10 seconds, FLOW BLOCKED should be shown
