11.5 O2 Concentration Calibration
NOTE

Do not perform O2 concentration calibration while the unit is connected to a
patient.
 Make sure that the system is Standby. If not, push the Standby key to enter
standby screen.
Calibrate the O2 sensor when the measured O2 concentration has a great deviation or when
the O2 sensor is replaced.
Follow these steps to calibrate the O2 sensor:
1. Make sure that Air and O2 supplies are connected.
2. Push the Menu key. Select [ Calibrate ] and select [ O2% ]. Select [ Calibrate ] on the
right side to start O2 sensor calibration. The message [ Calibrating ] is displayed.
3. During the calibration, if you select [ Stop ], the ongoing calibration will stop and the
message [ Calibration Stopped! Calibration is unfinished. ] is displayed.
4. After a successful calibration, the screen shows [ Calibration Completed! ]. 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, check for technical alarm and troubleshoot it if there is.
Then do the calibration again. In case of repeated calibration failures, replace the
O2 sensor and do the calibration again. If it still fails, contact your service
personnel or us.
 Handle and dispose of the O2 sensor according to your biohazard policies. Do not
incinerate.
