What is the difference between the grounding resistance tester and the grounding resistance tester?
Earth conduction resistance tester, referred to as conduction tester, is a device that uses high current principle to test the enclosure of electrical equipment and the safe grounding of wire, so as to check the quality of the grounding of equipment
The earth resistance tester is called an earth resistance instrument, which is the instrument that uses the principle of potential compensation to test the contact resistance between earth wire and earth (ground resistance), so as to check the laying quality of the earth wire
