Troubleshooting

Symptom	Possible Cause	Corrective Action
No output signal	Power supply/wiring	Check power supply voltage; verify wiring connections; check fuse.
Erratic readings	Process conditions/wiring	Check for pulsations; verify proper grounding; inspect cable shielding.
Zero drift	Temperature effects/aging	Perform zero calibration; check ambient temperature; verify mounting stress.
Span error	Calibration/reference	Recalibrate span; verify reference standard accuracy; check for leaks.
HART communication failure	Resistor/configuration	Verify 250 ohm resistor; check communicator configuration; inspect connections.

Reset: Use reset function in configuration menu to restore factory settings.
