Solution: Verify 4-20mA input wiring and power supply; check air supply pressure and pneumatic line for leakage.
Solution: Run one-button Quick-Cal auto-calibration; inspect valve stem linkage and position sensor for mechanical misalignment.
Solution: Switch gain setting to "HI FRIC" mode; filter compressed air supply to clean contamination inside the pneumatic relay.
