Answer Posted / deepak kumar
for DPT calibration on the field :
1.at first go the field and check our tag number to which u calibrate
2.then first close the both HP & HP side isolation valve,open the equaliser valve
3.open the vent valve
(for zero triming there is pressure flow)
4.then connect the HART communicator at ve and -ve terminal
5.open the hart =>>device setup=>>diagnosis=>>calibration=>>sensor calibration =>>dp trim=>>then enter Zero trim at atmospheric pressure
(that solve)
NOTE:-after complete the calibration close it to it's normal conditions..
.
thanx...
