The Multi Function Calibrator is useful for the calibration of Digital Multimeters, Clamp Meters, Digital Panel Meters, Analog Panel Meters and Tachometers. It is a variable source with different ranges of DC Voltage, AC Voltage, DC Current, and AC Current. It has been designed to cover the calibration of maximum ranges of a variety of models of Multi meters available in the market.
The calibrator gives output, which is very stable. Stability is suitable enough to calibrate 4½ and 4¾ DMM and Clampon Meters. By using this source along with a high-resolution standard Multimeters user can calibrate even 5½ DMM. Calibrator has a micro controller unit, which handles all the parameter selection and range selection logic. Micro controller drives to the set of relays as per the logic program. Relays rout the outputs
