Product Description

GDCR3200C  clamp type portable digital earth resistance tester


Product Description
 

GDCR3200C is specially designed and manufactured for on-site measurement of earth resistance, soil resistivity, grounding voltage, ground wire leakage current, AC current and DC resistance. It adopts 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-diameter current clamp design,  can measure  the grounding system with large grounding down-conductor, and can flexibly and accurately measure various complexities such as single point and mesh grounding. Any grounding resistance value of the grounding condition, it is not necessary to disconnect any parallel grounding electrode when parallel grounding measurement, to maximize the convenience of measurement. The introduction of FFT (Fast Fourier Transform) technology, AFC (Automatic Frequency Control) technology, unique anti-jamming capability and environmental adaptability, repeated test consistency, ensuring high precision, high stability, and high reliability for years of measurement. It is widely used in grounding resistance, soil resistivity, grounding voltage, alternating current and leakage current measurement of electric power, telecommunications, meteorology, oil field, construction, lightning protection, and industrial electrical equipment.
GDCR3200C double clamp multi-function grounding resistance tester, also known as double-clamp grounding resistance tester, double-clamp grounding resistance meter, consists of main unit, current clamp (double clamp), data software, test line, auxiliary grounding rod, communication line and so on. The host has a large LCD display with backlight and bar graph indication briefly.
