How many terminals do you have on the transducer? And do you have the wiring diagram for it? Normally you will have an input 2 wires (10-30vdc) and an output 2 wires (4-20ma). Two in. Two out. No common. To test the output MA, put meter in series with one output conductor. Use the MA setting on the meter. Depending on how sensitive you need this, you may need to adjust the DC input or if provided the adjustment screw on the transducer.
