digital meter calibrator
Detailed Product Description
1 Summary
SF-1050W Single-phase Meter Calibrator is an electronic intelligent single-phase AC/DC meter calibrator designed according to related national standards and regulations. It can calibrate and test class below 1.0 single phase AC/DC ammeter, voltmeter, milli-ammeter, milli-voltmeter, frequency meter. This calibrator is composed of 3 parts: signal generating system of single-chip,
precision power supply and standard meter system. With standardized cabinet and featured by compact size, light weight, multi-function, high stability & automation, top reliability, it is an ideal calibrating equipment for AC/DC meters.
2 Feature:
2.1. Adopt single chip to digitally complete frequency modulation, amplitude modulation and phase modulation.
2.2. Adopt film switch, all the functions are completed by key-operating, equipped with fine voltage regulation and fine current regulation, digitized display providing objective and convenient view.
2.3. With automatic circuit protection for voltage short circuit and current open circuit to avoid damaging the equipment.
