AEMC 4630 Digital Ground Resistance Tester Kit - 500ft
Easy-to-use — simply connect the leads, Press-to-Measure and read the results. The large LCD (nearly 3/4" high characters) is easy-to-read, and also indicates low battery status, overrange 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 AEMC 4630 Digital Ground Resistance Tester is fuse protected up to 250VAC against accidental connection to live circuits. In the event of a system fault, it 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.
The AEMC 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 and will perform over 2000 15 second tests between recharging.
The AEMC 4630 Ground Resistance Tester is a rugged, easy-to-use instrument ideal for maintenance crews performing numerous tests. The AEMC 4630 exceeds mechanical and safety specifications for shock, vibration and drop tests called out in IEC standards. Designed to reject high levels of interference, so it can be used under difficult conditions such as high stray currents that normally affect accuracy.

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 in circumstances 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 in evaluating electrical safety. This test is recommended when the ground cannot be disconnected, where ground faults are highly likely to occur, or when the "footprint" of grounded equipment is comparable to the size of the ground to be tested.
- Two-Point tests
for continuity tests on bonding or on pre-established grounds. This
test is commonly performed in urban environments where proper auxiliary
electrode placement may be obscured by confined real estate.
Measurements
are referenced against a good local ground conductor.
