pressure transmitter:
in bench calibration connect a power supply 24v.give a
250ohms as loop resistance.connect a multimeter in
milliamph mode and connect it in series.and put a
communicator across the loop.the transmitters HP&LP sides
should be in open to atmosphere.this condition the
ammeter shows 4ma and the communicator shows LRV .connect a
pressure calibrator to the HP side and LP keep it open to
atm.apply pressure as the range and go on as 25%,50%,75%and
URV.then the ammeter shows 4,8,12,16,20ma
respectivly.incase you are not getting zero,make zero trim.
