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.
NIBP will not measure or is inaccurate
HighSymptoms: Times out, cuff will not inflate or hold pressure, readings implausible or fail against a reference.
Root cause: Internal pump or valve, a cuff / hose leak, or pressure-transducer / calibration drift.
Cuff / hose fault
MediumSymptoms: Slow inflation, air leak, will not hold, artefact-heavy readings.
Root cause: Split cuff bladder, a cracked hose, or a loose connector.
Motion / artefact rejection poor
MediumSymptoms: Frequent retries or error on moving patients (common on ABPM).
Root cause: Algorithm limits plus a marginal cuff fit or transducer noise.
Battery / power fault
MediumSymptoms: Short run time, will not power on or hold a 24 h ABPM study.
Root cause: Aged battery.
Data download / clock fault (ABPM)
LowSymptoms: Study will not download, timestamps wrong.
Root cause: Download cable / dock or the internal clock battery.

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: NIBP inaccurate or times out
- Leak-test the cuff and hose (occlude and watch for pressure decay).
- Run the device's pressure-calibration verification against a calibrated manometer.
- Confirm correct cuff size and placement.
- Verify against a NIBP simulator.
- Refer the pump / valve / transducer for service if it persists.
Symptom: Fails a 24 h ABPM study
- Fit fresh batteries and confirm capacity.
- Check the cuff and hose for leaks.
- Confirm the programmed schedule and that the study downloads.
- Replace the battery / clock cell.
- Verify against a simulator before re-issuing.
