1. Characteristics
Digital ground resistance tester, also known as three-wire ground resistance tester, ground resistance meter, etc., is a commonly used instrument for testing and measuring ground resistance. It adopts an extra large gray screen backlight display and microprocessor technology. It is a new generation of ground measuring instrument that replaces the traditional megger measurement to meet the requirements of two-wire and three-wire test resistance. Suitable for telecommunications, electric power, meteorology, computer rooms, oil fields, power distribution lines, tower transmission lines, gas stations, factory grounding grids, lightning rods, etc. Instrument testing is accurate, fast, simple, stable and reliable.
The digital ground resistance tester is controlled by a microprocessor and the large<>gray-white screen displays the resistance value at a glance. At the same time, the group data is stored. Resistance measurement range: .&;~&; Ground voltage range: ~. It has functions such as value retention and alarm prompts.
