Low voltage measurement failure analyzer

Brief introduction

Low voltage measurement failure analyzer is development and research by our company, it is set electricity and electric measurement, watt-hour meter calibration, CT turn ratio measurement and failure analysis integration of the high accuracy measuring instrument.
The instrument match with high precision, high linear degrees, the amount of the limited width clamp ampere transformer, field wiring is simple, do not need to open direct access to power.
Menu operation and matches Chinese suggest, liquid crystal display, the man-machine dialogue friendly interface, operation simply, fast. More parameter display, watt-hour meter calibration, CT turn ratio measurement, real-time search measurement device failure, correct measurement, fill up power provides favorable testing method.
