4.3.4 Electronic Flowmeter Calibration (factory)

NOTE

Before calibrating the electronic flowmeter, verify if the electronic flowmeter

configuration displayed is same to the actual flowmeter configuration of the

anesthesia machine at the start-up. Make sure that no technical alarm occurs. If

there is, eliminate the technical alarm as per 5Troubleshooting and then perform

calibration.

When replacing the electronic flowmeter board or the flow restricting device of the

electronic flowmeter, or detecting that the deviation between the measured value of

the electronic flowmeter and that of the standard flow measurement device exceeds

10% or 0.1 L/min (whichever is greater), you need to calibrate the electronic

flowmeter again.

4.3.4.1 Calibration Procedures

NOTE

Before calibrating the electronic flowmeter, make sure that the breathing system

leak test in mechanical ventilation mode is already passed, so as to ensure that all

the gases flowing through the electronic flowmeter module pass through the low

flow inlet of the anesthesia machine calibration device.

When calibrating the electronic flowmeter of one gas, turn off other gases or

disconnect other gas supplies.

1. Perform leak test of the breathing system in mechanical ventilation mode and make sure

that the test is passed.

2. Zero the anesthesia machine calibration device as per the method for factory flow

calibration.

3. Use communication cable B to connect the calibration communication connector of the

calibration device with that of the anesthesia machine (also the CIS power connector), as
shown below.
