Air Calibration
WARNING: THE ANALYSER IS SENSITIVE TO OXYGEN PARTIAL PRESSURE. TO
ENSURE YOU ARE RECIVING THE MOST ACCURATE READING, CALIBRATION
MUST ALWAYS BE CARRIED OUT AT THE SAME ATMOSPHERIC PRESSURE AS
OXYGEN MEASUREMENT.
Air calibration is essential before every use and is performed as follows:
1.
Ensure that the sensor saver is not in place and that the EII adapter is fitted. The
adapter simply pushes into the sensor aperture.
2.
Expose the analyser to clean air for two minutes and adjust the calibration knob
until the display reads the correct value using the oxygen compensation chart (you
can find this chart on the inside of the back cover). If this is not possible refer to the
note below or to Sections 4.0, Quick Check and 5.0, After Sales Service.
The Analyser is now ready for oxygen management.
NOTE: AT VERY HIGH ALTITUDE, IT IS POSSIBLE THAT NORMAL CALIBRATION
IS NOT ACHIEVABLE. FOR USERS WHO INTEND TO USE THE ANALYSER AT
ALTITUDE, PLEASE REFER TO OUR WEB SITE FOR ADDITIONAL TECHNICAL
INFORMATION.
