Mabis LEGACY Aneroid Sphygmomanometer
Mabis · Model LEGACY Aneroid Sphygmomanometer
Mabis LEGACY Aneroid Sphygmomanometer with Black Nylon Cuff The MABIS Legacy Series provides quality aneroid Sphygmomanometers that deliver the performance and reliability that healthcare professionals depend on.
Key tips
- ·A no-signal/flatline alarm gets checked on the patient first, not the monitor - rule out a real clinical event before troubleshooting.
- ·Recalibrate NIBP against a reference manometer, not just a self-test pass.
- ·Reused patient cables (SpO2, ECG leads) are a common source of intermittent-fault complaints - swap the cable before the module.
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.
- ·Routine cable and lead-wire inspection for fraying/wear
- ·Battery conditioning cycle
- ·NIBP calibration check against a reference manometer
- ·ECG / SpO2 accuracy verification against a patient simulator
- ·Annual electrical safety test
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.
