6.10 Calibrating transmitters

6.10.1 Using the mA measurement function

GB
The mA function enables the user to read out the 4 ... 20 mA output from the device being
calibrated. This can be done passively – where the device under test directly generates 4-20 mA
and can be read by the calibrator.

6.10.2 Calibrating a pressure-to-current transmitter

To calibrate a pressure-to-current transmitter (P/I), perform the following:
1) Connect the calibrator and the pump to the transmitter.
2) Apply pressure with the pump.
3) Measure the current output of the transmitter.
4) Ensure that the read value is correct. If it isn't, the transmitter must be adjusted.
