Description
The Digital Ground Resistance Tester Model 4620 performs ground resistance and soil resistivity tests. This direct reading testers measures from 0 to 2000Ω, 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.
The Model 4620 is also available in complete kit form, which includes instrument, two 150 ft, 300 ft or 500 ft color-coded leads on spools (red and blue), one 30 ft lead (green), two 14.5″ T-shaped auxiliary ground electrodes, one set of five spaded lugs, 100 ft tape measurer and carrying bag.
