PM7221 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. When the meter is left idle for five minutes, the meter will automatically be shut down to extend the batteries’ service life. It can only be installed and operated by qualified specialists in accordance with the safety precautions and regulations and the required technical specifications. The calibrator can provide current output in accordance with Milliampere value or percentage displayed.
