rooms, oil fields, power distribution lines, transmission lines of iron
towers, gas stations, factory grounding networks, and lightning rods.
The clamp ground resistance tester is controlled by the
microprocessor and can accurately detect the ground resistance. It
uses a fast filtering technique to minimize interference. At the same
time data storage and data upload functions
