Measurement Parameter Operation Tests

ECG Operation

1. Press the Power Button to turn on the monitor.

2. Connect the ECG 3 lead wires to appropriate terminals on the ECG simulator.

3. Connect lead wires to the ECG cable.

4. Connect the ECG cable to the ECG connector on the monitor’s right panel.

5. Set the ECG simulator as follows:

z Heart rate: 30bpm

z Amplitude: 1millivolt

z Lead select: II

z Normal sinus rhythm

z Adult mode

6. After normal power-up sequence, verify the following monitor reactions:

a. After about 15 seconds, the monitor displays a heart rate of 30±1bpm.

b. Verify that the audible alarm sounds and that “Low Heart Rate/Pulse Rate

limits violated” message displays on the message area.

c. Verify that the HR/PR numerical area flashes and that the heart rate is below

the default lower alarm limit (medium priority alarm).

7. Increase the heart rate setting on the ECG simulator to 240bpm.

a. After about 15 seconds, verify that the monitor displays heart rate of 240±1bpm.

b. Verify that the audible alarm sounds and that “High Heart Rate/Pulse Rate

limits violated” message displays on the message area.

c. Verify that the HR/PR numerical area flashes and that the heart rate is above

the default upper alarm limit (medium priority alarm).

8. Decrease the heart rate setting on the ECG simulator to 120bpm.

a. After about 15 seconds, verify the monitor displays heart rate of 120±1bpm.

9. Disconnect the LL lead from the ECG simulator.

a. Verify that the “ECG Leads Off” message appears, that three dashes are

displayed in the HR/PR numerical area, and that the medium priority alarm

sounds.

b. Reconnect the LL lead to the ECG simulator. Verify that “ECG Leads Off”

message no longer appears and that the audible alarm is stopped.

c. Repeat this test for the LA and the RA leads.

10. Connect all the leads to the ECG simulator.

a. Select the ECG Waveform Menu and set Lead Select to Lead I.

b. Verify that the lead selection is displayed on the ECG waveform area.

c. Repeat step 10-a for all the ECG Lead selections.

11. Set ECG Lead selection to Lead II.

12. Change ECG waveform size to all the selectable sizes and verify that an appropriate

size is displayed on the ECG waveform area.

13. Disconnect 3 ECG leads and connect 5 ECG leads.
