4. When the system is standby, select Main-> Service-> Diagnostic Tests->Valves to
access the following menu.
5. Set Safety Valve to On.
6. Set PEEP Valve Pressure to 30 cmH2O.
7. Set Insp Valve Flow to the following values: (3±0.5)L/min, (10±1)L/min, (20±1)L/min,
(30±2)L/min, (60±3)L/min
Make sure that the deviation between the measured data of the inspiratory flow sensor, expiratory
flow sensor and ventilator flow sensor and that of the anesthesia machine calibration device must
not exceed 1 L/min or 5% of the measured value of the calibration device, whichever is greater.
Otherwise, perform flow calibration again.
Reinstall the bellows and the water collection cup. When testing the flow accuracy of (60±
3)L/min, only compare the accuracy of the inspiratory flow sensor and expiratory flow sensor.
It is no need to compare the ventilator flow sensor.
