AEMC 6472 Multi-Function Ground Resistance Tester
The Model 6472 measures from 0.01 to 99.99k Ω and is auto-ranging, automatically seeking out the optimum measurement range, test frequency and test current. Easy-to-use – Simply connect the leads, select test mode, press Start and read the results. Up to 512 test results can be stored in internal memory for recall to the display or downloaded to a PC via DataView® software.
The large LCD is easy-to-read and indicates ground electrode resistance, test voltage, current and frequency as well as individual electrode resistance, battery status and more.
The Model 6472 is Cat IV rated to 50V and is over voltage protected to more than 250Vac against accidental live connection to live circuits. The voltage is also displayed on screen. In the event of a system fault, the Model 6472 can withstand 250Vac.
Additional features of the Model 6472 include; manual and automatic test frequency selection from 40 to 5078Hz; user selectable 3 or 4-Pole Fall of Potential or 4-Pole Soil Resistivity test methods and user selectable 2-Wire or 4-Wire Bond Resistance test method.
The Model 6472 is powered by 9.6V, 3.5 Ah NiMH rechargeable batteries. An external recharger powered from 120/230V, 50/60Hz is included and provides for testing while recharging.
Features:
-
2- and 4-Wire Bond Resistance/Continuity Measurement (DC Resistance) with automatic polarity reversal

Applications:
- 3-Point measurements of resistance to ground of ground rods and grids. 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 an economical grounding installation.
- Touch and step potential testing measurements. These tests are recommended when the ground cannot be disconnected, where ground faults are highly likely to occur, 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 250mA 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.
