Earthing is a commonly known term for those who study current or electricity. It is an important component of current, and therefore, its measurement is also required importantly. Earth tester is a device used for measuring the earth resistance and record it for better implementation. This is done by measuring the resistive capability of the soil. If the soil resists as per the company’s set standard, then they can take actions to conduct their work there.
These testers should be handled only by high-level professional electricians or engineers. Current flow is not a game and should be taken seriously while handling.
