9.5 Pro O2 Analyzer Operation
Prior to each Analyzer use:
1) Connect the battery powered pump. Before switching on and during the warm up, air
must be flowing over sensor for proper calibration. The flow rate of air must equal 1.0 –
5.0 L/min.
2) Turn unit on by holding on/off button until display shows “On”, after that the “Att” (Wait)
message will be displayed for about 4 seconds, and then the sensor auto-calibration
procedure is started.
3) The auto-calibration last about 5 seconds; during this time the display will show the
message “CAL” and “Att” alternatively. Be sure during this time the sensor is exposed to
an air mix with oxygen percentage as programmed in the O2c (calibration) parameter
(SEE PROGRAMMING PROCEDURE). By default, for simplicity, the O2c value is set at
21% that corresponds to the percentage of Oxygen in free air.
4) At the end of the warm up and calibration, the display will continuously show the oxygen
content of the air flow. The instrument is now ready to read oxygen concentration of the
gas.
Gas, even under moderate pressures, can cause extreme bodily harm. Never allow any
gas stream to be directed at any part of your body.
Tip:
You can check the battery life and current temperature by holding Adjust button for 3
seconds. The display will alternate from battery life to current temperature (Celsius) twice before
returning the home screen.
Never expose the sensor to pressures above atmospheric pressure (0 psi) or you may
cause damage to the sensor and/or receive false readings. Damaged Sensors will not
provide accurate gas analysis. Inaccurate gas analysis can lead to serious personal
injury or death.
