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.
Constancy / accuracy / linearity QC out of tolerance
HighSymptoms: Daily constancy or quarterly accuracy/linearity checks trend out, activity readings off vs the reference source.
Root cause: Ionization-chamber gas or pressure change, electrometer drift, or a contaminated well/liner.
High or unstable background / zero fault
MediumSymptoms: Background will not zero, noisy readings at low activity.
Root cause: Electrometer leakage, chamber contamination, or nearby radioactive sources.
Remote display / chamber communication loss
MediumSymptoms: Readout unit does not see the remote or the chamber, no activity value.
Root cause: The long interconnect cable (up to ~30 m) or a connector fault.
Printer fault
LowSymptoms: No NRC-record printout or syringe/vial labels.
Root cause: Printer cable, paper, or the optional printer.

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: QC check out of tolerance
- Repeat the check with the sealed reference source in a clean well liner.
- Confirm no stray sources are near the chamber and the background zero is current.
- Run the built-in self-diagnostics.
- If accuracy/linearity still fail, contact Capintec for chamber recalibration or service.
- Document the QC results and any corrective action.
Symptom: No reading / comms loss
- Check the interconnect cable and both connectors at the readout and the chamber.
- Reseat the plug-and-play chamber connection.
- Try a shorter/known-good cable if available.
- Power-cycle the readout unit.
- If it still will not communicate, refer for service.
