Download the Product Manual Description: The FR2000+ Series Clamp-On Ground Resistance Tester is an advanced instrument developed by our skilled technical team. Featuring a modern LCD black screen backlight display and microprocessor technology, it offers simultaneous Ω and A displays. This tester provides a convenient and fast induction method for measuring grounding resistance without the need to disconnect ground wires or use auxiliary electrodes, ensuring a safe and efficient process. Widely applicable in telecommunications, electric power, meteorology, computer rooms, oil fields, power distribution lines, tower transmission lines, gas stations, factory grounding grids, and more, the FR2000+ excels in providing accurate, fast, simple, stable, and reliable measurements. The FR2000+ is managed by a microprocessor for precise ground resistance and leakage current testing. Its fast filtering technology reduces interference and can store up to 300 data sets simultaneously.
