The earth tester allows for quick and accurate measurement of loop resistance to ensure that, in the event of a fault current, there is sufficient resistance to ensure a safe shutdown. Additionally, measuring the protective conductor resistance allows for checking the continuity of conductors and connections. A graphical representation of the wiring helps the operator perform measurements accurately.
