We have an Absolute Pressure transmitter:
Range 0 to 1500mbara (4 to 20mA O/P).

The transmitter allows me to calibrate either:

0 mbara = 4mA or
1500mbara = 20mA or
0 = 4mA and 1500mbara=20mA.
(Ref:ATM pressure=1005.

Please, help me with the calibration procedure.

Thanks,
F. De Souza

Since this is smart device , you need HART protocol device like the HART COMMUNICATOR.
In this case, you need tp put tha parameters of the transmitter apprppriately including your desired seting values
or
You can implore the use work bench callibrator like the dead weight tester with gauge range 0-2000mBar and pneamatic regulator and a multimeter.

You cannot use dead weight tester for this range. Calibrate wityh HART communicator is OK. But will not varify the real life measurements. You need a stangard gauge/precision calibrator of 0~1500mbarA or suitable range. You can set up with a vaccum pump and some valves to get the same thing.
