Ground / Earth Continutity Testers

Ground/ Earth Continuity Tester is an instrument designed to verify the continuity of the ground (earth) connection in electrical system and equipment. This mainly used to ensure the safety compliance. This unit generates a 30A sinusoidal AC current, measures the voltage drop, and calculates the resistance of the ground path using the four-terminal method. It comes with digital display meters and front-panel indicators for pass/fail status. The test current will be delivered through a 3-pin socket with high-current carrying cable and earth pin. Unit comes with timer for setting the test duration from (typically 1 to 60 seconds)- test durations can vary as per different testing standards of different products.
