Resources
The AEMC 4620 4-Point Digital Ground Resistance Meter measures soil resistivity and ground resistance. Measures from 0? to 2000? with an auto-ranging feature to automatically seek out the optimum measurement range. Resists vibration, shock, and drops up to par with IEC standards. Denies high levels of interference to ensure accurate measurements.

Applications:
AEMC 4620 4-Point Ground Earth Resistance Tester
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
