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 “Testing the Patient Leadwires” on page 59 for more
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
Refer to the operator’s manual for this system to verify the correct operation of the
system.
When trying to isolate a system issue, perform the following steps
1. Verify that the system passes the power-up self test.
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.
Power Up Self Test
On power-up, the system automatically runs an internal self-test. If all tests pass,
you see the following start-up screen.
The next screen to open depends on the Power Up mode selected in System
Configuration . The Resting ECG mode is the default Power Up mode.
