The monitor automatically performs a self-test upon startup. During the self-test, you can hear the alarm tone, and the
alarm lamp glows yellow and red. This indicates that the visible and audible alarm indicators operate properly.
5.4 Module Performance Tests
5.4.1 ECG Test and Calibration
5.4.1.1 ECG Performance Test
Tools required:
Patient simulator Medsim300B
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, and amplitude = 1 mV.
3. Verify that 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 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.
5.4.1.2 ECG Verification
Test tool: vernier scale
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 that of the scale. The difference should be less than 5%.
5. After completing the calibration, select Stop Calibrating ECG.
5.4.2 Resp Test
Tools required:
Patient simulator Medsim300B
1. Connect the patient simulator and the monitor using a non ESU-proof cable and set lead II as the respiration lead of
the monitor.
2. Configure the simulator as follows: lead II as the respiration lead, the base impedance line as 1500 Ω, the delta
impedance as 0.5 Ω, and the respiration rate as 40 rpm.
3. Verify that the Resp wave is displayed without any distortion and the displayed Resp value is within 40±2 rpm.
