AEMC 4620 Ground Resistance Tester Tester 4-Point Digital Battery Powered

The digital ground resistance Tester 4620 model performs ground resistance and soil resistivity tests. This direct reading testers measures from 0 to 2000ù, and is auto-ranging, so it automatically seeks outs the optimum measurement range. The 4620 model is rugged, easy-to-use and is ideal for maintenance crews performing numerous tests. It exceeds mechanical and safety specifications for shock, vibration and drop tests called out in IEC standards. It is designed to reject high levels of interference, so it can be used under difficult conditions such as high stray currents that normally affect accuracy. Includes: meter, battery, and AC power cord. Measures soil resistivity (4-point) method measures ground resistance (2- and 3-point) fall-of-potential method step voltage tests and touch potential measurements auto-ranging: automatically selects the optimum range designed to reject high levels of noise interference extremely simple to operate: connect - press - read LED on faceplate informs operator of high input noise, high auxiliary rod resistance and fault connections battery powered rugged, Dustproof and rainproof field case can also be used for continuity tests on bonding color-coded terminals.
