ETCR EM2300B Ground Pile Clamp Earth Resistance Tester, also known as ground pile clamp tester, which is used for measurement of the earth resistance,soil resistivity, earth current,earth voltage. The tester has various measurement methods such as clamp tester method, two-wire method, three-wire method, four-wire method, and selection method. The tester introduces FFT (fast Fourier transform) technology and AFC (automatic frequency control) technology. It has unique anti-interference ability and environmental adaptability. The consistency of repeated tests is strong to ensure the high precision, high stability and high reliability of the measurement. The ground pile clamp earth resistance tester adopts large-caliber current clamp design, which can meet the test needs of various occasions, can measure the earth resistance value of large-size grounding down lead, can measure the earth resistance value of various complex grounding structures such as single-point and mesh grounding, and there is no need to disconnect any parallel connection of grounding electrode when measuring parallel connection of grounding systems, which greatly improves the convenience of measurement and provides a perfect solution for grounding performance testing.
