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.
Fails calibration / calibration-syringe check
HighSymptoms: 3 L syringe check outside tolerance, volume / flow drift over the day, biological control out of range.
Root cause: Flow-sensor contamination or wear (pneumotach / turbine / ultrasonic), a leak, or ambient (BTPS) correction not set.
Flow-sensor fault / leak
MediumSymptoms: Erratic traces, poor repeatability, back-extrapolated volume errors.
Root cause: Worn or wet flow sensor, a damaged filter seat, or a leak in the tubing / mouthpiece connection.
Gas-analyser fault (DLCO / lung volumes)
MediumSymptoms: DLCO or FRC results implausible, gas-analyser calibration fails, drift.
Root cause: CO / CH4 / He / tracer analyser drift or an analyser fault, or a demand-valve / gas-supply issue.
Plethysmograph door / pressure-transducer fault (body box)
MediumSymptoms: Box pressure will not stabilise, thermal drift, door-seal leak.
Root cause: Door seal, the box pressure transducer, or thermal equilibration.
PC / software / printer fault
LowSymptoms: Test hangs, results will not save, print or export.
Root cause: Workstation PC, software, or the printer.

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: Fails the calibration-syringe check
- Confirm ambient temperature / pressure / humidity are entered and BTPS correction is on.
- Fit a fresh flow sensor / filter and repeat the 3 L syringe check at several flow rates.
- Leak-test the sensor-to-mouthpiece connection.
- Run a biological control (a healthy known subject).
- Replace the flow sensor if it will not hold calibration.
Symptom: DLCO / lung-volume results implausible
- Run the gas-analyser calibration and check for drift.
- Confirm the test-gas cylinder is correct and not empty.
- Leak-test the breathing circuit and demand valve.
- Run a biological control.
- Replace the analyser cell or refer the analyser if calibration will not hold.
