10. If the calibration is finished successfully, the message [
Calibration Completed!
] is
displayed. Otherwise, the message [
Calibration Failure! Please try again.
] is
displayed. In this case, you need to do the calibration again
.
NOTE

If the calibration fails, you can select [
Defaults
] to restore the factory default
calibration values. If the deviation is great, select [Calibrate] again to do a
calibration.

If the calibration still fails, replace the AG module.
7.3.9.3 Commonly-encountered Problems and Recommended Actions
Failure description Possible cause Recommended action
Calibration menu is
inaccessible. The AG module is not fully warmed up
or not in measure mode. Wait for the AG module to be
fully warmed up and then access
the calibration menu.
Calibration is not
completed. 1. The module is damaged.
2. The difference between the set AG
calibration concentration and the
selected standard AG concentration is
too great. 1. Return the module to factory
for repair.
2. The difference between the
standard gas concentration and
the set calibration concentration
cannot exceed 25% of the
standard gas concentration.
7.3.10 O2 Module Calibration (factory)
7.3.10.1 Preparations
Calibrate the O2 module once a year or when the measured value has a great deviation. Prepare
the following before doing the calibration:
 Gas cylinder with 100% O2 and the O2 concentration not less than 99%.
 T-shape connector
 Tubing
7.3.10.2 Calibration Procedures
NOTE

Do not calibrate the O2 module when there are significant leaks in the airway.

In case of calibration failure, select [
Calibrate
] again to do a calibration.

If the calibration still fails, replace the O2 module.

Calibrate the O2 module, if it has been transported for long distance or if you
suspect it does not work properly.
Follow this procedure to perform a calibration:
1. Make sure that the system is not Standby and the AG module is in [
Measure
] state.
2. Wait for the AG module to be fully warmed up.
3. Select
