The WZ-1030E single-phase AC/DC standard source is a calibration source for LED five and a half digit display of AC/DC voltage and current. High output power and strong load capacity; Equipped with an RS232 interface, it can be connected to a computer network. The system software design is reasonable and complies with the new national metrology regulations; Implement automatic processing of test data; The unique protection circuit makes the operation of the calibrator safer and more reliable.

This calibrator is mainly suitable for verifying and calibrating various current and voltage meter heads and corresponding precision multimeters below level 0.2. It can also be used as a high stability testing power supply, and can be used in conjunction with a high-grade standard meter to calibrate current and voltage meters above level 0.2.

Single phase precision testing power supply, single-phase AC/DC standard source, single-phase programmable precision testing power supply, precision AC/DC testing power supply, single-phase AC/DC standard source.
