ERITECH® EST401 Ground Resistance Tester
The handheld ERITECH® EST401 Ground Resistance Tester measures ground rod and small grid resistance in any season without the use of auxiliary ground rods. The tester can measure the resistance to ground, verify the quality of the grounding connections and bonds, and can measure the resistance and continuity of grounding loops around pads and buildings.
The ERITECH EST401 includes a current-measurement function. The probe’ s high sensitivity enables measurement of current leakage flowing to ground or circulating in ground loops down to 1 mA and neutral currents to 30 Arms. A rugged Lexan® body and a double-walled Lexan shell ( or equivalent polycarbonate) to encase the probe heads, offers strength and durability. Overall construction and mechanical design ratings meet or exceed IECSM standards. The product has been designed to meet IEC 1010.
Battery life information is given at power-up and auto-off and a large LCD makes viewing resistance and current-measurement easy. The ERITECH EST401 is ideal for measuring ground current and ground resistance at pole ground rods, service entrances, pad-mounted transformers, transmission towers, service panels, phone pedestals and central office locations. Extended distances between installations, such as high-tension towers, will not adversely affect the measurement results.
