Description
The AEMC 4620-500 4-Point Digital Ground Resistance Meter Kit 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. This 500 ft Kit includes the AMEC 4620 along with four 14.5" T-shaped auxiliary ground electrodes, two 500 ft color-coded leads on spools (blue and red), two 100 ft color coded leads (black and green), one 30 ft lead (green), 100 ft tape measure, one set of five spaded lugs, and carrying bag.

Applications
Applications: AEMC 4620-500 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
