GE HealthCare Marquette Case 16
GE HealthCare · Model Marquette Case 16
12 SL Stress Test with Treadmill Stroke-written display exposes waveform variations User-defined measurements assures accuracy.
Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Noisy ECG / lead-off during a stress test
HighSymptoms: Baseline wander, muscle / motion noise, "lead fail", ST measurements unreliable.
Root cause: Poor skin prep, dried or lifting electrodes, a worn acquisition (CAM / patient) cable, or EMI from the treadmill.
Treadmill / ergometer control fault
MediumSymptoms: CASE cannot control the treadmill or bike, protocol will not advance, speed / grade error.
Root cause: Treadmill control cable / interface, or a treadmill drive / grade fault.
Acquisition module / workstation fault
MediumSymptoms: Channels drop, the CASE application hangs, test will not start.
Root cause: Acquisition (CAM) module or the workstation PC.
NIBP fault (if fitted)
MediumSymptoms: Exercise BP times out or is implausible.
Root cause: NIBP pump / valve or a cuff / hose leak.
Report printer / connectivity fault
LowSymptoms: No printed report, or reports will not send to MUSE / the EMR.
Root cause: Printer, or the network configuration.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Follow the manufacturer's PM schedule
- ·Perform incoming and annual electrical safety testing per facility biomedical program
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Noisy ECG during stress
- Re-prep the skin and fit fresh stress electrodes.
- Secure the lead wires and use a patient-cable pouch.
- Swap in a known-good acquisition (CAM) cable.
- Check treadmill grounding and EMI.
- Confirm a clean 12-lead at rest before starting the protocol.
Symptom: CASE will not control the treadmill
- Confirm the treadmill powers on and runs from its own controls.
- Check the control cable between CASE and the treadmill.
- Verify the treadmill type is configured in CASE.
- Test protocol advance.
- Replace the control cable or refer the treadmill drive as isolated.
