Clamp Earth Tester Has Automatic Self Calibration Capability


Toronto, Canada – GAO Comm has announced the release of its handheld single clamp earth tester which simplifies ground loop testing and enables non-intrusive leakage current measurement. It is widely used in telecommunication system, electric power system and in the fields of resistance testing for earth resistance of various equipment and buildings.

This portable single clamp earth tester, model A0E10001, goes beyond the limitations of traditional methods of earth resistance testing as it does not require the disconnection of the ground wire. Earth ground loop testing and continuity testing can be completed without breaking the circuit. It offers a wide ground loop resistance range from 0.01 to 1000 O and performs integrated value of ground resistance and also tests the leakage current of ground wires. The clamp earth tester features easy operation, high accuracy measurement, automatic self-calibration ensuring correct measurement and anti-interference capabilities. The tester is equipped with a 4 bits digital LCD display screen and provides a memory capacity of 50 groups of results.

This handheld single clamp earth tester belongs to GAO's family of Earth Ground Testers. This line of products also includes Double Clamp Earth Resistance Tester which offers self-check function and automatic frequency control (AFC) function, Handheld Earth Ground Tester and Portable DC Ground Fault Locator is able to efficiently perform fault testing for indirect grounding, non-metal grounding, loop grounding, positive and negative grounding, positive and negative balance grounding, and multipoint grounding in DC systems.
