The grounding resistance tester is a common instrument for testing and measuring grounding resistance. It is also an indispensable tool for electrical safety inspection and grounding engineering completion acceptance. In recent years, due to the rapid development of computer technology, the grounding resistance tester has also penetrated a large number of microprocessor technology , Its measurement function, content and accuracy are incomparable with ordinary instruments. The current advanced ground resistance tester can meet all grounding measurement requirements. The use of the new jaw method eliminates the need for piling and laying out for online direct measurement. A powerful ground resistance tester is controlled by a microprocessor, which can automatically detect the connection status of each interface and the interference voltage and frequency of the ground network, and has unique functions such as value retention and intelligent prompts.

Why is ground resistance still a problem that is ignored by everyone? The main reason is that there is no ideal measuring instrument. The ground shake meter of the high-speed labeling machine has poor test value accuracy due to well-known reasons. Sometimes the same connection resistance of the ground resistance tester becomes an abstract physical quantity, which is difficult to predict. With the development of scientific instruments, advanced ground resistance testers have completely controlled the essentials of ground resistance testing, and the test values can be correct. At present, the intelligent grounding resistance meter is not only powerful; it can also cope with various complex situations on the spot, such as effectively eliminating interference, automatically tracking the most suitable test piece, and prompting intelligent prompts for various problems.
