Failure Description
Possible Cause
Recommended Action
machine calibration device. Set the
anesthesia machine again if necessary.
The prompt message
"Calibration Failure!
Please try again." is
displayed 15 minutes
after calibration is
started.
Calibration data is incorrect
Replace the inspiratory and expiratory
flow sensors and conduct calibration
again. If calibration still fails, replace
the VCM.
When the flow reaches 90
L/min, the collected AD value
of the inspiratory flow sensor
or expiratory flow sensor is
larger than 3900, which is out
of the normal range.
1. Replace the flow sensor in the
circuit.
2. Replace the VCM.
[00000002] is
displayed
Drive gas pressure is low.
1. Check the drive gas supply.
2. Check the drive gas switch if the
drive gas supply is in proper
condition.
[00000004] is
displayed
The Auto/Manual switch is in
Manual position.
1. Check whether the Auto/Manual
switch is set to the Auto position.
2. Check whether the Auto/Manual
switch can be set normally.
[00000008] is
displayed
There is a zero point error for
the inspiratory flow sensor.
1. Check whether fresh gas is turned
on.
2. Check whether the inspiratory
valve is switched off: After the
inspiratory valve is switched off
(DA=0 on the valve diagnosis tool),
the AD value of the sensor on the
anesthesia machine does not change
(or the change is within 1%) when the
gas supply is connected and
disconnected. This indicates the valve
is switched off.
3. Check the correctness of the zero
point for the sensor.
4. Replace the VCM.
[00000010] is
displayed
There is a zero point error for
the expiratory flow sensor.
1. Check whether fresh gas is turned
on.
2. Check whether the inspiratory
valve is switched off: After the
inspiratory valve is switched off
(DA=0 on the valve diagnosis tool),
the AD value of the sensor on the
anesthesia machine does not change
(or the change is within 1%) when the
gas supply is connected and
disconnected. This indicates the valve
is switched off.
3. Check the correctness of the zero
point for the sensor.
4. Replace the VCM.
