2. Wait until the CO2 module warmup is finished, and check the airway for leakage and perform a leakage
test as well to make sure the airway has no leakage.
3. In the [ CO2] menu—->CO2setupselect [Zero].
4. Connect the test system as follows:
5. Open the relief valve to vent standard CO2 and make sure that there is an excess gas flow through
theT-shape connector to air.
6. Check the realtime CO2 value is within 6±0.05％ in the [zero CO2] menu.
6.4 ECG Test
6.4.1 ECG Performance Test
Tool required:
Fluke Medsim 300B, MPS450 or other patient simulator recommended
Follow this procedure to perform the test:
1. Connect the patient simulator with the ECG module using an ECG cable.
2. Set the patient simulator as follows: ECG sinus rhythm, HR=80 bpm with the amplitudes 1mV.
3. Check the ECG waves are displayed correctly without noise and the displayed HR values within 80 ± 1
bpm.
4. Disconnect each of the leads in turn and observe the corresponding lead off message displayed on the
screen.
5. Set that the simulator outputs paced signals and set [PACE] to [ON] on the monitor’s patient manage
interface. Check the pace pulse marks on the monitor screen.
