UT278C/D Earth Clamp Meter, also called Loop Resistance Tester, is used for grounding resistance test. It has multiple functions such as clamping measurement, 3- or 4-wire measurement, voltage/current measurement, data storage/viewing, alarming, auto power off and more. With fast filtering technology employed, interference can be minimized. Designed with 2.4-inch color screen, UT278C/D is characterized by aesthetic appearance, easy to carry, wide range, high resolution, stable performance, strong anti-interference ability. It is mainly used to measure ground resistance of power distribution lines, gas stations, grounding grids, lightning rods, telecommunication, electric power, meteorology, oil fields and others.
