5.5.1 (5 ½) Digit Multi Function Calibrators

5.5.1 (5 ½) Digit Multi Function Calibrators
Multi Function Calibrator / Voltage & Current Standards

We are Manufacturer, Supplier, Exporter of 5.5.1 (5 ½) Digit Multi Function Calibrators, Multi Function Calibrators / Voltage & Current Standards and we are also specialized in Calibration Services. Our setup is situated in Pune, Maharashtra, India.

The Multi Function Calibrator is useful for the calibration of Digital Multimeters, Clamp Meters, Digital Panel Meters, and Analog Panel Meters. 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 41/2 and 43/4 DMM and Clampon Meters. By using this source along with a high-resolution standard Multimeters user can calibrate even 51/2 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.

Features
  • Pure Sine wave with variable frequency.
  • Overload and short circuit protec.
  • Setting by Decade switches for V/A in 5½ digit.
  • Frequency setting by potentiometer.
  • Separate output ports for V(Hi), mA(Hi), 10A(Hi) & Com.
  • Parameter and range selection by inbuilt micro controller based unit and relays. Bar of LEDs to indicate parameter and range.
