6. Push the pushrod of the syringe to make the reading of the anaesthesia machine
calibration apparatus rise to 70-90 cmH2O. Stop pushing the pushrod and remain the
relative position between the pushrod and the syringe body unchanged. If the pressure
reading of the anaesthesia machine calibration apparatus decreases no more than 5
cmH2O within 15s, the test item is passed.
II. Leakage test on the pressure sampling line of the flow sensor inside the system (If test item I is
not passed, conduct this test)
1. Fix the test fixture of the circuit transit adapter to the circuit transit block assembly.
2. Connect the pressure sensor interface (positive pressure end) of the anaesthesia machine
calibration apparatus, syringe (pull out the pushrod to a certain position before
installation), and the test fixture of the circuit transit adapter to the corresponding
connectors of the Silicon hose (6x300) (the connector except for connects 1 to 6 on the
test fixture) using the Y-shape tube.
