Quickstick Oxygen Analyzer Operation Manual
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.
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, as detailed in the
Appendix, or dry air must be used for calibration.
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.
Calibration in air at sea level is suitable for many applications; however, the closer the oxygen content of the
calibration gas is to the gas being tested, the more accurate the measurement results. The following special
applications require calibration procedures beyond the scope of this manual:
•
Analysis of gases containing greater than 50% oxygen requiring calibration with pure oxygen or
certified calibration gas
•
Analysis of gases at altitudes above sea level requiring correction for reduced atmospheric pressure
3.1. Air calibration is essential before every use and should be performed in the environment that the
reading will be taken.
3.2. The calibration adjustment screw is the only user adjustable control on the O

. It is
located in the recessed hole on the battery end of the Analyzer.
3.3. The Calibrator Trim Tool provided is used to calibrate the Analyzer. It uses a very small flat
screwdriver blade to adjust the calibration screw.
3.4. Expose the analyzer to fresh air for two minutes or until the reading on the display has stabilized.
Adjust the calibration screw with the calibrator trim tool until the display reads 20.9% (see Section 4).
