AEMC Instruments 3640 Datasheet & Stock

AEMC 3640 Offers

The AEMC 3640 Digital Ground Resistance Tester performs ground resistance measurement. Easy to use - simply connect the leads, press to measure, and read. The large LCD (nearly 3/4" high) also indicates low battery status, overrange, and lead reversals.

The 3640 comes with 3 color coded terminals to aid in easy hookup. Three LED indicators on the front panel continuously warn the user of measurement problems to ensure accurate and reliable tests.

Applications

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.
