Introduction：

Multifunctional grounding resistance tester is also called grounding resistance tester. It is an advanced grounding resistance tester which integrates various measuring methods. The large-size high-definition segment code LCD screen display and microprocessor technology are adopted, and the grounding resistance test is measured by microprocessor-controlled 3-wire method and simple 2-wire method. Widely used in telecommunications, electric power, meteorology, computer rooms, oil fields, power distribution lines, tower transmission lines, gas stations, factory grounding grids, lightning rods and so on. The instrument has the characteristics of accurate, fast, simple, stable and reliable test.

The multifunctional grounding resistance tester is controlled by microprocessor, which can accurately detect grounding resistance, soil resistivity, grounding voltage and DC voltage. It uses fast filtering technology to minimize interference. The resistance value of auxiliary electrode is displayed on the same screen, which is convenient for judging the measurement error caused by environmental factors and measuring the real resistance value of grounding more accurately. At the same time, 500 groups of data are stored, and the functions of wireless or wired remote measurement, reading historical data, exporting report analysis and so on are realized by connecting the mobile phone APP through Bluetooth or connecting the PC through USB. It has unique functions such as value keeping and intelligent alarm prompt.

The multifunctional grounding resistance tester is composed of host computer, upper computer software, mobile phone APP software, test cable, USB cable, charger and grounding pin.
