Troubleshooting
Do the following:
• Check for defective, broken, or disconnected leadwires.
• Run the Patient Leadwire diagnostic test to verify that each leadwire is
functioning properly. See
information.
• Check for defective or expired electrodes.
Additionally, you can use the Hookup Advisor to monitor ECG signal quality. It can
help you pinpoint whether the noise is caused by leadwire failure, baseline shift,
muscle artifacts, power line interference, baseline wander, or electrode noise. This can
point you to the correct areas for additional troubleshooting. Refer to Chapter 7,
Recording a Resting ECG, in the MAC™ 2000 ECG Analysis System Operator's Manual
for more information.
General Fault Isolation

2.
Conduct a visual inspection of the system.
3.
Review the system event log for errors, warnings, and informational messages
that will help you identify and isolate system problems.
4.
Perform diagnostic tests.
Each step is described in more detail in the following sections.
