But I guess it is like this: 1) supply positive 2) signal 3) supply ground You connect it just like a 4-wire transmitter. The coding block must be set as for a 4-wire transmitter. The signal is connected to M+ measurement input. The third wire is also the return for the signal (where you have a fourth wire in a 4-wire transmitter). To compensate the lack of the 4th wire, put a jumper between the measurement input M- and supply ground M.
