ETCR3200 Double Clamp Earth Resistance Tester, through a variety of methods measuring earth resistance (range: 0.01Ω ~ 30.00 kΩ), soil resistivity (range: 0.01Ωm ~ 9000kΩm), earth voltage (range: 0.1 V ~ 100.0 V), grounding lead leakage current, AC current (range: 0.01mA ~ 600A); The tester adopts the precision 4-wire method, 3-wire method, simple 2-wire method, selection method and double-clamp method to measure grounding resistance. Large caliber current clamp design, can measure the grounding system which using large grounding down lead.It can flexibly and accurately measure arbitrary grounding resistance values of single point and mesh grounding and other complex grounding conditions. When measuring parallel grounding, it is unnecessary to disconnect any parallel grounding electrode to maximize the convenience of measurement. Import FFT (fast Fourier transform) technology, AFC (automatic frequency control) technology, ensure the measurement of  high precision, high stability and reliability.

ETCR3200 Double Clamp Multi-function Grounding Resistance Tester is composed of host machine, current clamp, monitoring software, test wires, auxiliary ground rod and communication cable. Host machine with large LCD display, white backlight, bar chart indication, clear at a glance. It can store 2000 sets of data at the same time, through the monitoring software to relize historical access and online real-time monitoring functions, dynamic display, alarm indication and auto shut down, with historical data reading, accessing, saving, reporting, printing and other functions.
