ZMSMFC 4.5 4½ Multifunction Site Calibrator


Applications

Multifunction Calibrator is useful for the calibration of Digital Multi Meters, Clamp Meters, Digital Panel Meters, Analog Panel Meters, LCR Meters, and Non-Contact Type Tachometers. It is a variable source with different ranges of DC Voltage, AC Voltage, DC Current, AC Current, Frequency, Resistance, Capacitance, Inductance & RPM (Non-Contact Type). 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 issuitable enough to calibrate 31⁄2 and 33⁄4 DMMs and Clamp- on Meters. By using this source along with a high-resolution standard Multimeters user can calibrate even 41⁄2 DMM.


Features

- Pure Sine wave with variable frequency
- Input supply Under Voltage and Over Voltage Protection
- Overload and short circuit protection
- Setting by Decade switches for V/A in 41⁄2 digit
- Frequency setting by multi turn potentiometer
- Selection of AC/DC parameter by toggle switch
- Selection of ranges by rotary switch
- Separate output ports used for V(Hi), mA (Hi), 10A(Hi) & Com
- Separate output ports used for R / L / C
