5. FRD Sensor FD3051SDP Differential Pressure Transmitter Measurement Accuracy Troubleshooting Guide
If abnormal output signals or inaccurate readings occur, troubleshoot as follows: 1. Check if the positive and negative impulse lines and valves are clear and leak-free; 2. Calibrate the transmitter zero point, and perform zero trimming via HART communicator or buttons if necessary; 3. Confirm whether the working static pressure and ambient temperature are within rated limits; 4. Check if the power supply voltage is stable (meets the 24VDC requirement).
