Does anyone know of a reason that would prevent accurate readings on a plant DCS when supplying it with a 4-20mA signal from a USB-3104? We have confirmed that the plant DCS is accurate. We have also confirmed that the mA output from the USB-3104 is accurate, but when the two are connected together the readings are not even in the same ballpark. We're connecting to a Delta V DCS.
