27. Check that the ALARM light is OFF.
28. Press MAIN MENU.
Part 2— Electrical Check
Use the same setup for this check described in “Setup” on page 17.
1. Set the patient simulator to provide pacer signals.
2. If the pacer indicator is not on, press ECG/RESP > MORE and select and change the
pacer setting.
3. Check that a dashed vertical line is displayed on the ECG waveform each time a pacer
pulse occurs.
4. Set the oscilloscope to 0.2 second/division sweep and 0.5 Volt/division amplitude.
5. Insert a short piece of thin conductive wire into each of the ECG X1000 connector
holes shown in the figure below or use real time ECG Out cable 008-0320-00.
6. Connect the scope probe and the scope ground clip to the wires.
7. Check that the scope displays an ECG signal with an amplitude of 1 V ±100 mV
baseline to peak of R-wave.
8. Move the wire and scope probe from the ECG pin of the ECG X1000 connector to the
DEFIB SYNC connector pin shown in the figure below or use Defib Sunc Output
cable, 008-0237-00. Leave the scope’s ground clip where it is.
9. Change the vertical sensitivity of the scope to 1 Volt/division.
10. Check that the scope displays a 5 V p-p pulse with a 100 ±5 ms width.
Note
Some amount of mains noise may also be present in the signal.
