WebFeb 6, 2016 · Most instruments feedback a 4-20mA analog signal to the PLC inputs. Now if I'm in the field taking a voltage measurement with a multimeter at the output terminals of a transmitter what reading should I expect? I would have expected to see between 1 and 5v. On some transmitters I do get a 1-5v reading but others I just see 24v. WebIf you set it to 20m, then the highest current you can measure its 20mA. If you are on 20mA and it says 0.5, that probably means you are measuring 0.5mA. There exist auto-ranging multimeters which you simply set to current mode and you don't have to worry about picking a range. Share Cite Follow answered Nov 9, 2012 at 19:54 NickHalden
