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.
Cannot obtain / hold cuff pressures
HighSymptoms: Segmental cuffs will not inflate or hold, pressure leaks off, study will not complete.
Root cause: Worn cuffs / tubing / connectors, an internal pump / valve fault, or a manifold leak.
PPG / Doppler sensor fault
MediumSymptoms: Flat or noisy PPG / PVR waveform, no Doppler signal.
Root cause: Worn PPG probe or Doppler probe, or a probe-cable fault.
Pressure-transducer / calibration drift
MediumSymptoms: Recorded pressures implausible or biased, calibration fails.
Root cause: Transducer drift or a calibration issue.
Software / PC / report fault
MediumSymptoms: Study will not save, calculate ABI, or generate a report.
Root cause: Workstation PC, software, or the interface.
Printer fault
LowSymptoms: No or faint waveform printout.
Root cause: Printer or paper.

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: Cannot hold cuff pressures
- Fit known-good cuffs and tubing.
- Occlude each channel and confirm it holds pressure.
- Check the manifold and quick-connectors for leaks.
- Verify pressures against a calibrated manometer.
- Refer the internal pump / valve manifold if leaks persist.
Symptom: Poor PPG / Doppler signal
- Swap the PPG / Doppler probe and cable.
- Confirm probe placement and skin contact / gel.
- Flex the cable while watching for dropout.
- Verify on a normal limb.
- Replace the probe if a known-good one works.
