suppose, after calibrating a transmitter we fixed it in a process line. At live zero condition the Tx shows 4.5 mA. what should we do to make the Tx show 4 mA? If we adjust zero, will it not affect the calibration?
Answer Posted / kashif
Isolate the Tx from process and fully depressurized it and checked if it reads 4 Ma then calibration is OK and carried out flushing of both impulse lines and gain take it in service it should read zero or 4 Ma.
