The 4-20 mA isn't what I need to produce. I need the 0-5AAC to supply the xdcr which in turn is converted to the 4-20 mA that I need to cal. The xdcr takes the 5AAC off the motor CT and sends the 4-20 out.
I'm actually not sure if the voltage is that big of and issue. I was comparing the imput signal another CT to another XDCR and it was 3AAC(at the time) at 175 mV. I just don't want to burn something out.
What I want to do is calibrate the 4-20mA output(to DCS net.) which is indicating...
I need to produce at 0-5AAC in the millivolt range to test a current to current transducer. The ac amp source to the XDCR is from a 150:5 CT which is then converted to a 4-20mA signal. If my company had the money I would go with an Arbitor panel meter calibrater but that's not an option...
