■ TH9403 type grounding resistance tester is used to measure the grounding resistance within the electrical equipment, which reflects the (contact) resistance between the exposed conductive parts of the electrical equipment and the total grounding terminal of the electrical equipment. Ground resistance tester in order to eliminate the impact of contact resistance on the test, the use of four-segment measurement method, that is, in the measured electrical exposed conductive part and the total grounding terminal plus the current between, and then measure the voltage between these two ends, calculated its resistance value. This product meets GB4706.1-2005, GB9706.1-2007 and other domestic and international safety standards test, in line with the requirements of JJG984-2004 safety measurement and verification regulations.
