RKI Instruments Gas Tracer - Manual (Page 155)

Gas Tracer Operator’s Manual Using Maintenance Mode • 147
If the ppm combustible sensor fails the bump test,
• The instrument will beep and a calibration is immediately and
automatically started. Continue to apply the calibration gas.
CAL on the bottom left of the screen will alternate with APPLY.
The calibration time will begin to countdown in seconds in the
lower right of the screen. The calibration time counted down
during a calibration initiated because of a failed bump test is
the difference between the bump test gas time and the
calibration time defined in the BUMP--SET menu item in
Maintenance Mode.
• At the end of the calibration, the instrument displays the
results from both the bump test and the calibration. Use the
AIR▲ or (SHIFT)▼ button to scroll between the calibration/
bump test results, the bump test gas reading, and the
calibration gas reading.
