Calibration Results
Once calibration is complete, the display either shows a “P” for pass or an “F” for fail for each
sensor. The display will alternate between the gas concentration and the letter “P” when the
monitor passes calibration. The “CAL” LED lights in green when calibration is passed. “CAL”
LED lights in red if there is a failure.
Instrument Connected
Once on, the display will show gas channels
and a transmit message. The gas monitor is
ready for a Bump Test or Calibration.
Bump Test
Press the “Bump” button to start bump test.
Note: Ensure calibration gas cylinder is connected
to a demand flow regulator and then to the back
of the cal station. Make sure calibration gas
concentrations match values shown on display.
Bump Gas Reading
During Bump test, the display
shows current gas reading.
Bump Results
The BUMP LED will stop blinking and be on
steadily green if the bump test passed or
steadily red if the bump test failed. Display
will show “P” for pass or “F” for fail for each
sensor. The display will alternate between
the gas concentration and the letter “P”
when the monitor passes bump test.
