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].
