Zero Sensors

Manual Zero Sensors

You can zero a sensor by using the atmosphere to reset the sensor’s baseline reading. Inert purge gas may also be applied to the manual calibration inlet to zero sensors.

Warning:

EXO’s sensors must only be zeroed with clean air. If a sensor is zeroed where its targeted gas levels are abnormal, the gas levels EXO displays will not be accurate. Inaccurate readings are a safety hazard.

  1. Ensure EXO is in clean air.
  2. Press the OK button to enter the main menu.
  3. Select Gas options.
  4. Select Zero sensors.
    A screen will prompt you to zero the sensors.
  5. Ensure all the gas sensors you wish to zero are selected.
  6. Select Start zeroing.
    Note:

    Do NOT apply gas.

    A message will indicate when the zeroing is completed.

If you see a “Zero incomplete” message on EXO’s screen:

  • EXO may be in an environment with abnormal gas levels.

  • EXO’s cartridge may need to be replaced.
