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.
Aneroid gauge out of calibration
MediumSymptoms: Gauge disagrees with a reference manometer, or the needle does not rest in the zero band with no pressure.
Root cause: Normal drift / shock to the Bourdon-tube movement; the gauge is generally not field-adjustable.
Cuff / bladder will not hold pressure
MediumSymptoms: Slow inflation, pressure bleeds down too fast, cannot maintain a reading.
Root cause: Split or perished bladder, a cracked tube, or a loose / worn connector.
Inflation bulb / valve stiff or leaking
MediumSymptoms: Bulb hard to squeeze or perished, release valve will not give a smooth 2-3 mmHg/s deflation, or leaks down.
Root cause: Perished bulb rubber or a worn / gummed control (release) valve.
Gauge face / glass / bezel damage
LowSymptoms: Cracked lens, loose bezel, needle fouling the face.
Root cause: Drop or crush damage.

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: Gauge reads inaccurately
- Connect the gauge to a calibrated reference manometer through a Y-piece with a closed volume.
- Check the zero: with no pressure the needle must rest within the zero band.
- Compare at several pressures across the range.
- Replace the gauge if it is outside tolerance (typically the movement is not field-adjustable).
- Log the calibration-check date.
Symptom: Cuff will not hold pressure / slow inflation
- Inspect the bladder, tubing and bulb for splits or perishing.
- Check the release valve seats and does not leak down too fast.
- Replace the bladder, bulb or valve as isolated, or the complete cuff.
- Re-test against a closed system for a slow, controllable release.
- Confirm the cuff size range suits the intended patients.
