Application

It is used to power grid corporation measuring and testing center, power supply company power supply management and energy metering department, national levels measuring and testing institutions, also suitable for large industrial and mining enterprises and property companies, etc

Introduction

GF112 handheld single-phase watt-hour meter for the verification is the scene of single-phase watt-hour meter on-line detection accuracy and design. But in constant electricity, don't take out stitches measure the electrical energy, power, current, voltage, frequency and power factor, Angle. The accuracy of the instrument adjusting rejected traditional methods of the potentiometer + screwdriver, internal by single chip microcomputer control, can not open the equipment in the case, through the button to complete precision adjustment, so as to enhance the reliability and stability. This instrument has small light, the function is all ready, use convenient, beautiful shape, and other features, is the ideal of single-phase watt-hour meter online testing instruments.

Main functions

Checking various inductive, electronic type of single-phase watt-hour meter error on site;

Having the cumulative power function, checking the single-phase watt-hour meter and LED value;

measuring voltage, current, power, power factor, frequency, and electric parameters etc;

To save 1000 group of measurement data, convenient inquires the calibration data;

With RS232 communication interface, and connecting computer on line to data management;

Optional current clamp 5 A, 20 A, 50 A ,100 A;

To measure CT ratio, measurement device than the integrated error.
