Descripción

Product description ETCR3200C Double Clamp Earth Resistance Tester, also known as multi-function earth resistance tester and precision earth resistance tester, which is used for measurement of on-site measurement of earth resistance, soil resistivity, earth voltage, down lead leakage current, AC current, and DC resistance.The tester adopts digital processing technology, precision 4-wire method, 3-wire method, simple 2-wire method, selection method, and double clamp method to measure the earth resistance, which can flexibly and accurately measure any earth resistance value of various complex grounding conditions such as single-point and mesh grounding. No need to disconnect any parallel grounding electrode during parallel earth measurement, which maximize the convenience of measurement. Introducing FFT (fast Fourier transform) technology and AFC (automatic frequency control) technology, it has unique anti-interference ability and environmental adaptability, and strong consistency in repeated tests to ensure high precision, high stability and high reliability of long-term measurement.It is widely used in electric power, telecommunication, meteorology, construction, lightning protection and industrial electrical equipment industries.ETCR3200C Double Clamp Earth Resistance Tester consists of a host, a current clamp (double clamp), data software, a test line, an auxiliary earth rod, and a communication line, etc. The tester adopt the design of large-caliber current clamp, which can meet the test need of various occasions, and can measure the earth resistance value of a large size earth down lead. The host has large LCD display with backlight and bar chart indication, which is clear. The tester has a storage function, a clock function, and automatically stores 2000 sets of test results containing date and time.Through the USB interface data software, historical data can be read, consulted, saved, reported, printed and other functions.
