Voltage current signal source (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. The calibrator can provide current output in accordance with Milliampere value or percentage displayed. The maximum voltage imposed between any input terminal and the ground or between two input terminals 30V. Storage temperature:-40℃ to 60℃. When the meter is left idle for five minutes, the meter will automatically be shut down to extend the batteries’ service life.
