Kyoritsu 4118A Digital Loop Impedance Tester

The Kyoritsu 4118A is a digital loop impedance tester that is able to measure prospective short current (PSC). Designed to comply with an IP54 rating, the 4118A is comprised of a custom microprocessor to achieve high accuracy and reliability.

Where the loop resistance of an earth circuit is too high and in the event of an overload or short circuit it is possible that that circuit breakers or earth leakage devices may become inoperative. To prevent such incidents, the earth circuit resistance must be measured to ensure it is sufficiently low.
