The Digital Ground Resistance Tester Model 4630 Kit performs ground resistance and soil resistivity tests. This direct reading testers measure from 0 to 2000O, and is auto-ranging, so it automatically seeks out the optimum measurement range. The Model 4630 Kit 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 Kit is powered by 9.6V, 3.5 Ah NiMH rechargeable batteries. A built-in recharge circuit, powered from 120/230V 50/60Hz line, also provides for testing while recharging.
The large LCD (nearly 3/4" high characters) is easy-to-read, and also indicates low battery status, over-range, and test lead shorts and lead reversals. Three LED indicators on the front panel continuously warn the user of measurement problems to ensure accurate and reliable tests. The Models 4620 is fuse protected up to 250VAC against accidental connection to live circuits. In the event of a system fault, they can withstand 250VAC with spikes of 3000VAC or 1000VDC.
The heavy-duty field case is sealed against dust and water when closed. The meter itself is self-contained within an inner case providing additional environmental and insulation protection. The test button is also sealed against the elements.
