1. An error occurs in the
pneumatic circuit connection
between the anesthesia machine
calibration device and the VCM.
2. An error occurs in the
communication connection

calibration device is set
incorrectly.
1. Check the pneumatic circuit
connection between the anesthesia
machine calibration device and the

The calibration data is incorrect:
The measured range of the sensor
is abnormal, the calibration data
does not satisfy monotonicity, or
the sensor resolution is incorrect.
For details, see section 3.7.5.
Replace the VCM.
