5.3.3 ECG Tests

5.3.3.1 ECG Performance Test
Tool required:

Fluke Medsim 300B patient simulator or equivalent equipment
Follow this procedure to perform the test:
1. Connect the patient simulator with the ECG connector 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. If the value
is not within 80 +/-1 then contact Mindray Technical Support
4. Disconnect each of the leads in turn and observe the corresponding lead off message displayed on the screen.
5. Set the output of the simulator to deliver a paced signal and set [Paced] to [Yes] on the monitor. Check the pace pulse
marks on the monitor screen.
5.3.3.2 ECG Verification
Tool required:

Vernier caliper
Follow this procedure to perform verification:
1. Select the ECG parameter window or waveform area→ [Filter]→ [Diagnostic].
2. Select [Main Menu]→ [Maintenance >>]→ [User Maintenance >>]→ enter the required password→ [Module
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%. If the difference is
not within 5% contact Mindray Technical Support.
5. After completing the verification, select [Stop Calibrating ECG].

5.3.4 Resp Performance Test

Tool required:

Fluke Medsim 300B patient simulator or equivalent equipment
Follow this procedure to perform the test:
1. Connect the patient simulator to the module using a non ESU-proof cable and set lead II as the respiration lead.
2. Configure the simulator as follows: lead II as the respiration lead, base impedance line as 1500 Ω; delta impedance as 0.5
Ω, respiration rate as 40 rpm.
3. Verify the Resp wave is displayed without any distortion and the displayed Resp value is within 40 ± 2 rpm.
