I have 3 strain gauge transmitters I need to bench test the 4-20ma output. The transmitter 4-20 side is two wire with a shield. I do have a known workiing strain gauge.
I have read several posts on how to create a 4-20ma signal with batteries, resistors etc. Can I test the 4-20 output using a standard DMM, batteries or a power supply to create the current loop?
