AEMC 6470 2135.03 Multi-Function Ground Resistance Tester Kit 300 Ft

The AEMC 6470 Multi-Function Ground Resistance Tester performs earth coupling measurements, grounding resistance, bonding tests, and soil resistivity.

The 6470 tester measures from 0.01 to 99,000 Ohms, and is auto ranging, automatically finding the best measurement range, test current and frequency. Simply connect the test leads, make your test mode selection, Press to Measure and read the results. Up to a maximum of 512 individual test results can be stored in memory for later review to the display or download to your PC for hard copy reports and analysis.

Applications

3 Point measurements of resistance to ground of grids and ground rods. 3 Point measurements are used when electrode or grid can be easily disconnected
4 Point tests or soil resistivity measurements. Locating areas of lowest soil resistivity is essential for achieving a feasible grounding installation
Touch and step potential testing measurements. These tests are best where ground faults are highly likely to occur, when the ground cannot be disconnected, or when the “footprint” of grounded equipment (the outline of the part of equipment in contact with earth) is comparable to the size of the ground to be tested
2 or 4 Wire tests for continuity tests on bonding or on grounding systems. Test is a DC resistive test using 250 mA or more and is used to check bonding of all connection points on the ground system
Earth coupling measurement and display. Used to estimate the influence of two earth resistance systems that are not connected to each other
