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.
Calibration / QC failure
HighSymptoms: Fault code on the LCD, a shift in clinical or QC values, or a failed detector-sensitivity test.
Root cause: Loss of the fixed-calibration status - contact ITC / Accriva Technical Service; do not attempt field recalibration.
Clot-detection / detector sensitivity fault
MediumSymptoms: Daily detector check fails, erratic clot times.
Root cause: Magnetic detector or optics in a test well degraded.
Test-well temperature out of range
MediumSymptoms: Results drift, temperature verification outside 37 C.
Root cause: Well heater or temperature-control fault.
Battery / power fault
MediumSymptoms: Low-battery early, will not run a full shift.
Root cause: Aged battery cells or a charger fault.

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: Fault code / shifted results
- Run multiple tests with HEMOCHRON control plasma at two levels.
- Perform the daily detector-sensitivity check.
- Verify the test-well temperature with the verification tube.
- If a calibration error is confirmed, contact Accriva / ITC Technical Service.
- Do not send the instrument for service before running the controls.
Symptom: Short battery life
- Fully charge on AC overnight.
- Note the continuous run time.
- Confirm the daytime-battery / overnight-charge routine.
- Replace the battery pack if run time is short.
- Re-verify run time.
