Overview

ETCR3200C Double Clamp Multi-function Grounding Resistance Tester is specially designed and manufactured for on-site measurement of grounding resistance, soil resistivity, grounding voltage, grounding line leakage current, AC current and DC resistance. Apply digital processing technology, precision 4-wire method, 3-wire method and simple 2-wire method, selection method, double-clamp method to measure grounding resistance; Large caliber clamp design can measure the grounding system which using large grounding down lead, and can flexibly and accurately measure any grounding resistance value of various complex grounding conditions such as single point and mesh grounding. It is not necessary to disconnect any parallel grounding pole to measurement, maximize the convenience of measurement. Import FFT (Fast Fourier Transform) technology, AFC (Automatic Frequency Control) technology, with unique anti-interference ability and environmental adaptability, high repeated test consistency, ensuring high precision, high stability and high reliability for long-term measurement. The tester case is made of waterproof protection box, anti-collision, anti-drop, waterproof (protection grade IP65), strong and durable, and also equipped with a large-capacity rechargeable lithium battery pack, especially suitable for outdoor construction. Widely used in power, telecommunications, meteorology, oil fields, construction, lightning protection and industrial electrical equipment, such as grounding resistance, soil resistivity, grounding voltage, alternating current, leakage current measurement.
