The AEMC 6418 [2141.03] Earth/Ground clamp, delivered in its carrying case, can be used for quick testing of earth loops, whatever their type. Its clamping capacity allows measurements on 30 x 40mm and 20 x 55mm rectangular bars and cables 32mm in diameter. The 6418 clamp simultaneously displays the earth-loop resistance and the leakage current. Due to ergonomic innovations such as the OLED display providing visibility over an angle of 180 degrees, in all lighting conditions, it is particularly easy to use. The automatic "pre-HOLD" function when the clamp is opened and the automatic calibration of the jaw gap at power-up ensure optimized processing of the measurements provided by the 6418 clamp.
