The ETCR EM3200C dual-clamp grounding resistance tester, also known as a multi-functional grounding resistance tester or precision grounding resistance tester, is used for on-site measurement of grounding resistance, soil resistivity, grounding voltage, grounding wire leakage current, AC current, and DC resistance. The instrument employs digital processing technology and supports precise 4-wire, 3-wire, simplified 2-wire, selection, and dual-clamp methods for measuring grounding resistance. It can flexibly and accurately measure any grounding resistance value under various complex grounding conditions, including single-point and mesh grounding. When measuring parallel grounding, no parallel grounding electrodes need to be disconnected, maximizing measurement convenience. It incorporates FFT (Fast Fourier Transform) and AFC (Automatic Frequency Control) technologies, possessing unique anti-interference capabilities and environmental adaptability. Its strong repeatability ensures high accuracy, stability, and reliability for long-term measurements. It is widely used in industries such as power, telecommunications, meteorology, construction, lightning protection, and industrial electrical equipment.

The ETCR EM3200C dual-clamp grounding resistance tester consists of a main unit, current clamps (dual clamps), data software, test leads, auxiliary grounding rods, and communication cables. The instrument features a large-diameter current clamp design, capable of meeting testing needs in various situations. It can measure the grounding resistance of large-sized grounding leads. The main unit has a large LCD display with backlight and bar graph indicators for easy reading. The instrument supports Bluetooth communication with Android systems; after installing the APP, testing and reading test records can be performed on mobile devices, providing a brand-new experience. The instrument has storage and clock functions, automatically storing 2000 sets of test results with date and time. Data software via USB interface allows for historical data reading, viewing, saving, reporting, and printing.
