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 / volume accuracy check fails
HighSymptoms: 3-L syringe verification outside tolerance, questionable FEV1 / FVC.
Root cause: Debris or condensation in the ultrasonic flow path, a damaged FlowTube / spirette, or transducer aging.
DLCO / gas-analyser drift or calibration fault
HighSymptoms: DLCO, TLC or FRC results drift, gas calibration fails.
Root cause: Gas analyser aging, a calibration-gas issue, a sample-line leak, or the demand valve / gas delivery.
PC / EasyWare communication fault
MediumSymptoms: Software will not connect, no data transfer.
Root cause: USB cable / port or driver.
Sample / breathing valve or filter fault
LowSymptoms: Leak at the mouthpiece, contamination flags, poor manoeuvres.
Root cause: Worn valve, or a reused single-use FlowTube / filter.

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: Calibration verification fails
- Fit a fresh FlowTube and dry any condensation from the flow path.
- Repeat the 3-L syringe check with smooth strokes at varied speeds.
- Confirm the environmental / BTPS settings.
- Run the gas-analyser calibration with the correct calibration gas.
- Re-verify and record the check.
Symptom: EasyWare will not connect
- Do not connect the device until the software is installed (needs Administrator rights).
- Reinstall EasyWare.
- Try another USB port / cable.
- Confirm the device is seen by the operating system.
- Re-test communication.
