• Battery powered
• Rugged, dustproof and rainproof field case
• Can also be used for continuity tests on bonding
• Color-coded terminals

Application: 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.

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.

Application: The Ground Resistance Tester Model 3640 is a rugged, easy-to-use instrument ideal for maintenance crews performing numerous tests. The Model 3640 is designed to reject high levels of interference. It can be used under difficult conditions such as high stray currents that normally affect accuracy. The Model 3640 may be used to perform the following tests: 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.
