5. Highlight each ECG Lead (I, II, III, and V) and verify that for each one:
• a waveform is present
• heart rate is 80 bpm ± 3 bpm
6. Remove one lead and verify that the monitor displays an equipment alert identifying
the failed lead: “Equipment Alert/ECG Fault/xx Lead failed”.
7. Replace the lead and wait for the waveform to reappear.
8. Repeat Step 6 and Step 7 for each lead.
9. Reconnect all leads.
10. Set the ECG simulator to a paced signal.
11. Set the monitor pacer indicator ON ( Setup > ECG > Pacer Indicator ).
12. Verify that the monitor ECG waveform displays the pacers as vertical dashed markers.
Respiration
1. Set the Resp parameters on the ECG simulator to:
• 20 breaths/minute
• breath size = 1 ohm
• base impedance between 200 and 1200 ohms
• Lead Select to lead I
2. On the monitor, turn on Resp.
3. Set the Waveform Source to Resp . (See Step 3 and Step 4 in “ECG” on page 58.)
4. Set the monitor Resp Lead to Ld1 (RA-LA) . ( Resp/min Resp Lead .)
5. Verify that the monitor displays a Resp waveform with a rate of 20 bpm ± 2 bpm.
6. Switch the respiration simulator lead to lead II .
7. Set the monitor Resp Lead to Ld2 (RA-LL) .
