PM7221 (Volt/mA Calibrator)is a Volt/mA source and measuring tool used in tests on 0-24 Milliampere current circuit and 10V DC voltage. This calibrator can not be used for measurement and output simultaneously. The calibrator can provide current output in accordance with Milliampere value or percentage displayed. Percentage range is from -25.00% to 125.00%. 0% corresponds to 4 Milliampere and 100% to 20 Milliampere. In the current source mode, the calibrator provide current, in the analog mode ,the calibrator simulates a group of two-wire transmitters using external current loop.
