Detail AEMC 4620 GROUND RESISTANCE TESTER
The Digital Ground Resistance Tester Model 4620 performs ground resistance and soil resistivity tests. This direct reading testers measures from 0 to 2000© , and is auto-ranging, so it automatically seeks outs the optimum measurement range. The Model 4620 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.

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
