Hi, I have been trying to build a 4-20 milliamp tester but I need soom help. I,m an Electrician and when it comes to semiconductors i,m a little lost. I work on equipment that uses 4-20 feed back. I want to build a simple tester i can plug into when i,m fault finding, calibrating. I have a 10K pot and a supply of resistors, but dont have the brains to work out where and what value resistors are required. Does anybody have a simple circuit i could use.
Thanks
Doug
