What could be the reason for a pressure transmitter to read zero even though the process is operational?
A. The pressure transmitter sensor failed B. The transmitter’s zero point is out of adjustment C. The transmitter’s span point is out of adjustment D. The transmitter’s wiring is damaged or loose
