Kyoritsu 4118A Loop Impedance Meter

The Kyoritsu 4118A Loop Impedance Meter is a custom microprocessor-controlled tester designed for precise loop impedance measurements. Manufactured by Kyoritsu, this device ensures the reliability and safety of electrical circuits.

In scenarios where the loop resistance of an earth circuit is too high, circuit breakers or earth leakage devices may become inoperative during an overload or short circuit. To prevent such incidents, it is crucial to measure the earth circuit resistance to ensure it is sufficiently low.
