I'm new to this, so I apologize in advance, I will get right to it. I have a fluke 87V and I've been troubleshooting my 4-20mA circuits and I'm not sure which way is correct. I turn my dial on my meter and put it to DC mA setting. I move the leads to the correct position on my meter for the mA. Now in my circuit we have 24v output on the white wire to the device and the device converts it to 4-20mA and sends it back to my plc on the black wire. If I'm trying to read that through my meter can I put my black lead on ground and the red lead on the wire sending 4-20mA back to my plc to get a proper reading or how would I put my leads to see what that device is sending out for a 4-20mA to my plc. If this is a basic question I apologize.
