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.
EtCO2 reading drift / needs zero
HighSymptoms: EtCO2 offset, slow response, or a zero-required prompt.
Root cause: Sample cell / airway adapter contamination or moisture, or IR bench drift.
No CO2 waveform
MediumSymptoms: Flat trace, occlusion or "check adapter" message.
Root cause: Blocked / kinked sample line, a full water trap, or a sample-pump fault.
Module not recognised by the host
MediumSymptoms: Host monitor does not display the capnography.
Root cause: Docking / connector or cable fault.
Sample-line / water-trap supply issue
LowSymptoms: Repeated occlusion or contamination flags.
Root cause: Reused single-patient line or trap, or wrong type.

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: EtCO2 value looks wrong
- Fit a fresh sampling line and water trap.
- Allow the bench to warm up and perform a zero in room air.
- Confirm the sample pump runs and the trap is not full.
- Verify against a reference CO2 concentration if available.
- Return to use only after a clean capnogram.
Symptom: No waveform
- Replace the sampling line and water trap.
- Check the line for a kink or blockage.
- Confirm the internal sample pump runs.
- Reseat the module at the host and check the connector.
- Confirm a normal capnogram.
