Before starting the
calibrations , ensure that the altitude setting (in "System Configuration" menu) is set to
the appropriate altitude forthe machine location.
For the "21% O 2 Calibration" software reads the AjD value for the O 2 sensor when 由e
O 2 sensor is exposed to room air (21 % O 2 ).
• If this AjD value is not within the tolerance , the calibration fails.
•
Ifthe calibration passes , the AjD value is stored in the EEPROM .
Th e sensor must be calibrated at 21 % O 2 before calibration at 100% O 2 .

Place the sensor that passed the 21% test in the breathing system and expose it to
100%0 2 .
If it displays readings higher or lower than requiredωpass， replace the sensor.
