If you want to source, simulate or simply measure, the Additel Loop calibrator series will fit your needs. The ADT209 and ADT210 allows for measurement of current, voltage and a switch. You can also simulate or source mA or a process transmitter. With the push of a button, you can switch to zero and span values, auto ramp, and auto step throughout the range. Each loop calibrator has a large, easy to read screen which simultaneously displays the measurement with the % of span.
