Note: Battery not Included During The Shipping !!!

Introduction:

Digital grounding resistance tester, also known as the three-wire grounding resistance tester, grounding resistance meter, etc., is a commonly used meter for measuring grounding resistance. It adopts a large LCD gray-white screen backlight display and microprocessor technology to meet the requirements of two-wire and three-wire test resistance.
Suitable for telecommunications, electricity, meteorology, computer rooms, oil fields, power distribution lines, iron tower transmission lines, gas stations, factory grounding networks, lightning rods and so on. Instrument testing is precise, fast, simple, stable and reliable.
The digital grounding resistance tester is controlled by the microprocessor and can automatically detect the connection status of each interface and the interference voltage and interference frequency of the ground network, and has the function of testing the auxiliary grounding resistance value. At the same time store 500 sets of data, resistance measurement range: 0.01Ω ~ 3000Ω, grounding voltage range: 0.01 ~ 600.0V
