The newly issued preventive test regulations for electric safety tools require that a group direct current resistance test must be regularly performed on a portable short circuit grounding wire and a personal protection grounding wire. The grounding conduction tester is a portable tester with high automation degree, and is specially used for measuring the direct current resistance of a portable short-circuit grounding wire and an individual protection grounding wire. The instrument is controlled by a high-performance single chip microcomputer, the intelligent testing process can be realized, the operation is simple and convenient, the precision is high, the testing speed is high, the retest performance is good, the reading is visual, the instrument is an ideal special instrument meeting the regulation requirements, the development of test items is greatly facilitated, and the working efficiency is improved. But one is: in the process of testing and connecting the grounding electrode, the protective layer and the rust of the grounding electrode need to be manually removed, and the process of keeping connection is slow at the moment of conducting parts, and the connection reliability cannot be guaranteed. Secondly, the following steps: at present, the grounding conduction detection is used for the connection of the grounding electrode and is manually held, and the high voltage generated by an instrument in the test process can possibly damage personnel holding the grounding electrode.

An effective solution to the problems in the related art has not been proposed yet.
