The Benning CM E1 grounding measurement clamp is a state-of-the-art handheld multimeter specifically designed for measuring earth loop resistance and leakage current. With its digital 4-digit LCD display, it enables precise and user-friendly measurement of earth loop resistances ranging from 0.025 ohms to 1500 ohms. The clamp does not require the disconnection of the ground or the use of ground spikes, significantly simplifying the application. It features automatic calibration upon startup and is equipped with both optical and acoustic alarm functions that activate when grounding resistances are too high. The grounding measurement clamp is also capable of measuring leakage, leakage, and load currents using TRUE RMS measurement methods, ensuring high accuracy. With an internal memory for 116 measurement values and a robust protective case, the Benning CM E1 is suitable for both professional use and private applications.
