7.1 Using the mA Input Function
The mA input function allows the user to read back 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.
7.2 Calibrating a Pressure-to-Current Transmitter
To calibrate a pressure-to-current transmitter (P/I), perform the following steps:
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 the reading is correct. If not, adjust the transmitter as necessary.
Warning
Check entity parameters before making any connections to this device.
