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.
Flow rate out of calibration
HighSymptoms: Flow error, counts not agreeing with a reference, flow-fault alarm.
Root cause: Vacuum pump wear or a mass-flow sensor / controller drift.
High zero count / fails zero-count check
HighSymptoms: Counts with the zero-count (purge) filter fitted exceed the limit.
Root cause: Internal leak past a fitting, or a contaminated optical chamber.
Laser / photodetector fault
MediumSymptoms: Laser-fault or reference-voltage error, no counts.
Root cause: Laser diode at end of life or a photodetector fault.
Printer fault
LowSymptoms: No printed count record, jams.
Root cause: Printer paper or head.

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: Flow fault / flow out of tolerance
- Verify flow with a reference flow meter at the inlet.
- Run the instrument's flow-calibration routine.
- Inspect the vacuum pump for wear.
- Replace the pump or recalibrate the flow controller.
- Re-verify flow and run a count comparison.
Symptom: Fails the zero-count check
- Fit the zero-count filter and run the check per the SOP.
- Leak-check the internal fittings and the sample inlet.
- Purge for the recommended time and re-run.
- Clean or service the optical chamber if counts stay high.
- Confirm a passing zero count before sampling.
