YC99T series is portable three phase meter testing equipment (calibrator), suit for lab and local use. YC99T series calibrator utilizes the testing technology with the lasted development of the energy meter calibration. YC99T5C has exactly software function as YC99T-3C calibration, but different voltage and current output.

YC99T-3C calibrator supports IEC standard communication protocol, and can complete demand indication error, demand period error, time switching error, rate period energy indication error and other multi-function test projects. YC99T-3C Calibrator has constant temperature crystal oscillator, which is able to verify the daily time error of electric energy meter.

YC99T-3C is designed with fantastic panels screen and wiring arrangement. The front and rear panel are designed to be easy-operating.

YC99T-3C not only provides normal meter testing, it also can be used as harmonic power output equipment, which is able to create stable harmonic output.

YC99T series Portable calibrator is capable of detecting daily time error of energy meter.
