data
were
empty. Or, the number of
calibrated electronic
flowmeters was less than
that of tubes configured.
1. Confirm and change the
electronic flowmeter until it is
correctly configured.
2. Calibrate the electronic
flowmeter again.

The electronic flowmeter
failed to communicate with
the main system normally.
1. Replace the communication
cable for the electronic flowmeter.
2. Replace the electronic flowmeter
board.

Gas flow exceeded 10
L/min.
1. Turn off other gas flow. Compare
the concerned gas flow with the
measurement result displayed on
the glass tube flowmter.
2. Use test tools. Turn on ACGO.
Measure fresh gas flow at the
inspiration connector. Measure the
measurement error of electronic
flowmeter.
3. If the error exceeds the standard,
calibrate the electronic flowmeter
again.
Flowmeter Zero
Failed
L
Zero point error or
three-way valve failure
1. Switch off fresh gas delivery.
Perform zeroing.
2. If the problem persists, check the
three-way valve component of the
electronic flowmeter module,
control circuit and cable.
3. Replace the three-way valve
assembly (throttling device).
4. Replace the electronic flowmeter
board.
Notes:
1. If special calibration equipment is not available, return the electronic flowmeter to the
factory for calibration together with the throttling device of the machine.
2. If the electronic flowmeter board is returned to the factory for replacement, the
throttling device of the machine must also be returned for replacement.
3. If special calibration equipment is available, you can just replace the electronic
flowmeter board. It can be used normally only after it is calibrated on the machine.
