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.
Haemodynamic pressure channel will not zero / reads wrong
HighSymptoms: IBP trace offset, "zero required" persists, pressures implausible.
Root cause: Transducer not open to atmosphere during zero, a damaged pressure cable, or an amplifier / acquisition fault.
ECG / intracardiac signal noise
MediumSymptoms: Surface or IC electrograms noisy, missing channels.
Root cause: Patient cable / junction box, catheter connections, or amplifier noise / grounding.
Acquisition amplifier / workstation fault
MediumSymptoms: Channels drop, the review workstation hangs, case will not start.
Root cause: Amplifier module or workstation PC fault.
Recording-system integration / display fault
LowSymptoms: No waveform to the lab displays or the recording system.
Root cause: Video / network output fault.

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: Pressure will not zero / reads wrong
- Open the transducer to atmosphere at the phlebostatic axis and re-zero.
- Flush the line and clear any air or clot.
- Swap in a known-good pressure cable.
- Move the channel to a spare input to isolate cable vs amplifier.
- Replace the cable or refer the amplifier.
Symptom: Noisy ECG / EGM
- Confirm electrode contact and catheter connections at the junction box.
- Check the patient cable for damage.
- Review lab grounding and EMI sources.
- Move affected channels to spare inputs.
- Replace the cable / junction box as isolated.
