mV Calibrator HandyCal 38500

The Digital mV Calibrators (HandyCal 38500) are handheld, battery-operated, precision instruments designed for sourcing as well as measuring mV signal. An exceptionally stable source provides continuously variable precision mV output signal with two ten-turn potentiometers. A self-check facility establishes correct functioning of all circuit blocks. They are specially designed for cost-effective mass calibration of a select subset of a various process control instruments and systems.
