There are two broad methods of Earth Ground-Resistance testing. Soil resistivity testers, often called earth testers, measure the ability of the soil itself to conduct electricity. Earth electrode testing measures the electrical connection between an electrical system and the earth. In earth electrode testing, there are four basic techniques fall of potential, direct, fall of potential without disconnection and stakeless measurement. Earth Ground-Resistance Testers are offered to perform earth testing or single and multiple forms of earth electrode testing. Earth ground testers perform the immensely important task of ensuring that in the event of a voltage spike or lightning strikes, electric currents pass safely through to the earth.
