| AEMC 4630-300 4-Point Ground Earth Resistance Tester Description: |
AEMC 4630-300 4-Point Ground Earth Resistance Tester 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.
It 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.
The Ground Resistance Tester Model 4630 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 Digital Ground Resistance Tester Model 4630 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.

| AEMC 4630-300 4-Point Ground Earth Resistance Tester Applications: |
| |
Three-Point measurements of resistance to ground of ground rods and grids. Three-Point measurements are generally used when the electrode or grid can be easily disconnected, if corrosion is suspected, or where ground faults are unlikely to occur
|
| |
Four-Point tests or soil resistivity measurements. Locating areas of lowest soil resistivity is essential for achieving an economical grounding installation
|
| |
Touch potential measurements, an alternative to 3-Point tests. A recommended test when the ground cannot be disconnected, where ground faults are highly likely, or when the "footprint" of grounded equipment is comparable to the size of ground to be tested
