Eearth tester

The MiG-like ground resistance tester is designed to measure resistance, except that the ground resistance is much lower than conventional insulation. Mega ohm and ground resistance tester is about ohm. The ground resistance tester is usually used to measure the resistance between two points of the earth is about 5 or 10 ohms. These equipments usually have three connections that can be made with the help of a metal rod. They are grounded and are known as current, ground, and potential electrodes.
