Analyzer Calibration
Oxygen Analyzers must be calibrated before each use. Improper calibration may result
in the use of incorrect breathing gas mixtures, which may cause serious injury or death
to the person using the gas mixture.
Calibration or use of the Analyzer with a low battery may result in inaccurate readings.
Inaccurate gas analysis can lead to serious personal injury or death.
When Analyzer calibration is performed at different atmospheric conditions than the gas
being measured, a calibration correction value may be required. Improper calibration
may result in the use of incorrect breathing gas mixtures, which may cause serious
injury or death to the person using the gas mixture.
If the Analyzer has been subjected to a recent change in ambient temperature, allow it to
stabilize for one hour before checking calibration.
During the warm up time if the oxygen percentage of the mixed gas flow is different from
the value of calibration set in the instrument, a failed calibration is obtained and a wrong
analysis value will be displayed.

Calibration Methods
Calibration should always be performed at the same temperature and humidity conditions as the
gas being measured. This is not always possible, for example, in a tropical environment where
dry breathing gas from a high-pressure scuba cylinder will be measured after Analyzer
calibration has been performed in the warm, humid ambient air. Under these conditions a
calibration correction value may be required, or dry air must be used for calibration. It may be
required for the analyzer to be auto calibrated to a certified calibration gas.
Obtain proper training before attempting special calibration procedures. Improper
calibration may result in the use of incorrect breathing gas mixtures, which may cause
serious injury or death to the person using the gas mixture.
To assure the greatest accuracy for other applications, use the calibration gas concentration
closest to the expected concentration in the gas being measured.
