3.4.1 ECG Tests and Calibration
ECG Performance Test
Tool required:
Fluke Medsim 300B 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 amplitude
as 1mV.
3. Check the ECG waves are displayed correctly without noise and the displayed HR value
is 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 [Paced] to [Yes] on the monitor.
Check the pace pulse marks on the monitor screen.
ECG Calibration
Tool required:
Vernier caliper
Follow this procedure to perform a calibration:
1. Select the ECG parameter window or waveform area→ [Filter]→ [Diagnostic].
2. Select [Main Menu]→ [Maintenance>>].
3. Select [Calibrate ECG]. A square wave appears on the screen and the message [ECG
Calibrating] is displayed.
4. Compare the amplitude of the square wave with the wave scale. The difference should
be within 5%.
5. After completing the calibration, select [Stop Calibrating ECG].
