AEMC 3640 Kit - 300 ft. 3-Point Ground Resistance Tester
The Model 3640 is also available in complete kit form which includes instrument, two 300 ft color-coded leads on spools (red and blue), two 100 ft color-coded leads (green and black), four 14.5" T-shaped auxiliary ground electrodes, one set of five spaded lugs, 100 ft tape measurer and carrying bag.
Measures ground resistance (2- and 3-Point)
Autoranging: automatically selects the optimum range
Designed to reject high levels of noise and interference
Extremely simple to operate: connect - press - read
LED on faceplate informs operator of high input noise, high auxiliary rod resistance and fault connections
Rugged dustproof and rainproof field case
May be used for continuity tests on bonding
Three-point measurements for measuring resistance to ground of ground rods and grids. Three-point measurements are generally used when the electrode or grid is easily disconnected, if corrosion is suspected, or where ground faults are unlikely to occur.
Two-point tests for continuity 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.
