4. Disable pacemaker pulse detection on the patient monitor and return
the simulator to these conditions:
 Heart rate – 80 bpm,
 Heart rate amplitude – 1.0 mV,
 5-leadwire ECG patient cable properly attached.
Leads Off Detection Procedures
1. Select ECG lead II to view in the top trace position on the patient
monitor display.
2. Disconnect the RA leadwire from the patient simulator.
3. Observe the following:
 an RA FAIL message appears on the display, and
 lead III automatically displays in place of lead II in the top trace
position.
4. Reconnect the RA leadwire to the patient simulator and discharge
the patient monitor.
Calibration Pulse Test Procedures
5. Inject a 1-millivolt calibration signal using the patient simulator and
start a manual graph.
6. Observe that the calibration pulse properly displays and graphs.
Compare the printed graph with the sample shown below.
7. Measure the cal pulse (Pulse) amplitude. These should be (+/-20%):
 Lead I:0.5 mV
 Lead II:1 mV
 Lead III:0.5 mV
 Lead V:-0.5 mV
8. This completes the 5 Leadwire ECG test. Leave the ECG patient
cable connected to ECG/RESP and continue to the next steps of
these checkout procedures.
