The earth tester allows for the quick and accurate measurement of loop resistance to ensure that, in the event of a fault current, sufficient resistance is present to ensure a safe disconnection. Additionally, a measurement of 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.
The earth tester offers a user-friendly interface, clear display elements, and a robust construction to meet the requirements in various environments. By complying with international standards, it ensures a safe and reliable assessment of electrical installations according to the highest industry standards.
