Product Description Feature of KDD400 Ground Resistance Tester:1. KDD400 is widely used in telecommunications, power generation, meteorology, computer rooms, oil fields, power distribution lines, tower transmission lines, gas stations, factory grounding grids, and lightning rods. The instrument features precise, fast, simple, stable, and reliable testing.2. Controlled by a microprocessor, the KDD400 accurately measures ground resistance, soil resistivity, ground voltage, DC voltage, DC resistance, and AC current. It utilizes fast filtering technology to minimize interference. The auxiliary electrode resistance value is displayed on the same screen, making it easy to identify measurement errors caused by environmental factors and enabling more accurate measurement of the true ground resistance. It stores 500 data sets simultaneously and connects to a mobile app via Bluetooth or a computer via USB, enabling wireless or wired remote measurement, access to historical data, and export of reports for analysis. It also features value hold and intelligent alarm notifications.3. KDD400 consists of a main unit, PC software, mobile app, test leads, USB cable, charger, and ground pin. Functions include two-, three-, and four-wire AC ground resistance, soil resistivity, three- and four-wire selection method, double-clamp resistance, DC resistance, AC voltage, DC voltage, and AC current.
