A sensor that cannot be calibrated or is found to be out of
tolerance should be replaced immediately. An instrument that
fails calibration may not be used until testing with known
concentration test gas determines that accuracy has been
restored, and the instrument is once again fit for use.
Possible causes and remedies for oxygen sensor failure:
1. Calibration gas cylinder does not contain a reduced level of oxygen. Verify that the cylinder contains 18.0% oxygen.

Cleaning
To challenge the oxygen sensor without calibration gas, hold you breath for about 10 seconds (or more, and then slowly exhale directly onto the face of the sensor (in the same way you would attempt to fog up apiece of glass. If the descending oxygen alarm is set to 19.5%, the instrument should go into alarm after a few seconds. Oxygen sensor has just been replaced and has not had time to stabilize.
