Hardware and Software Tests
18 Performance Verification
6. After normal power-up sequence, verify the following monitor reactions:
a. After at least five heartbeats, the monitor displays a heart rate of 30 ±5 bpm.
b. The audible alarm sounds and the
HEART RATE display flashes,
indicating heart rate is below the default lower alarm limit.
7. Press the ALARM SILENCE button. Verify that the audible alarm is
silenced.
8. Increase the heart rate setting on the ECG simulator to 240 bpm.
9. After at least five heartbeats, verify that the monitor displays a heart rate of 240
±5 bpm.
10. Verify that the audible alarm sounds and the
HEART RATE display flashes,
indicating that the heart rate is above the default upper alarm limit.
11. Press ALARM SILENCE button to silence alarm.
12. Decrease the heart rate setting on ECG simulator to 120 bpm.
13. After at least five heartbeats, verify that the monitor displays a heart rate of 120
±5 bpm.
14. Disconnect the LL lead from ECG simulator.
15. Verify that the
Leads Off alarm message appears, three dashes are
displayed in
HEART RATE display, and the low priority audible alarm
sounds.
16. Reconnect the LL lead to ECG simulator. Verify that the
Leads Off alarm
message no longer appears and audible alarm is silenced.
17. Repeat steps 14 through 16 for LA and RA leads.
18. Turn the monitor off.
Operation with a Respiration Simulator (A3 only)
1. With the monitor off, connect the ECG leads to the appropriate jacks on the
respiration simulator.
2. Connect the ECG leads to the ECG cable.
3. Connect the cable to the ECG input port on the monitor.
Note
The accuracy of A3 measurements is ±3 breaths per minute. In
the procedure below, add the tolerance of the simulator to the
acceptable range of readings.
4. Set the simulator for a respiration rate of 120 breaths per minute.
5. Press the ON/STANDBY button to turn the monitor on.
