KYORITSU 4120A

KYORITSU 4116A is a digital loop tester designed to measure loop impedance, prospective short circuit current, and voltage in electrical installations. It features a wiring check function with LEDs to indicate correct wiring, overload protection, and a large LCD display. The 4116A also has a D-LOK circuit that automatically locks most RCDs, eliminating the need to bypass them during testing. It operates without batteries, using the voltage from the system being tested.
