Dash 3000/4000 Patient Monitor
Revision A
2000966-339
Troubleshooting:
Data Acquisition Tests
ECG Waveforms Do Not Display At All
1. Test the ECG patient cables on a working monitor.
2. Test the patient simulator on a working monitor.
3. Swap the acquisition PCB into a working monitor. If the symptoms
follow the PCB into the working monitor, replace the acquisition
PCB.
4. If none of these first three steps provide any results, swap the
processor PCB and/or power supply PCB into a working monitor.
Lead Fail Functions
1. With the monitor displaying leads I, II, III, and V from the patient
simulator, remove the RA leadwire from the patient simulator.
2. The monitor should display a warning of a RA FAIL message. Lead
fail detection functions properly if this is the case. Lead fail detection
does not function properly if this is NOT the case. The acquisition
PCB is suspect. Swap the PCB with a working monitor to verify the
malfunction.
3. Reattach the RA leadwire to the patient simulator.
Pace Detect Functions
1. With the monitor displaying leads I, II, III, and V, set the patient
simulator to output a VP1 (ventricular pacemaker simulation #1)
waveform.
2. Enable the pacemaker detection function of the monitor.
a. Select
ECG
from the display main menu,
b. Select
DETECT PACE
and set to
PACE 2
.
3. Verify the heart rate remains at approximately 80 bpm.
4. Select the VP2 output (ventricular pacemaker simulation #2) on the
patient simulator.
5. Select and press
RELEARN
.
6. The heart rate number may disappear from the display for a few
seconds and return to the screen shortly thereafter. Verify the heart
rate is at approximately 80 bpm. Verify the pacemaker spikes display
at the same amplitude.
7. Disable the pacemaker detection function of the monitor. Verify the
displayed pacemaker spikes have a different amplitude than in the
previous step.
