Position Transmitter Calibration
Note
The position transmitter is calibrated at the factory and should not require calibration.
Note
This procedure will not move the control valve. The instrument will simulate an output for calibration purposes only.
This procedure is only available on units that have the optional position transmitter / limit switch hardware installed.
The DVC2000 digital valve controller is shipped from the factory with the position transmitter already calibrated.
To calibrate the position transmitter, select Transmitter Calibration from the Calibrate menu. Connect a current meter
in series with the +31 and -32 terminals, and a voltage source (such as the DCS analog input channel). Follow the
prompts on the Field Communicator display to manipulate the output current read by the current meter to 4 mA, and
then to 20 mA.
