AEMC 6472 KIT-150 FT - Multi-Function Digital Ground Resistance Tester Kit

6472 Multi-Function Ground Resistance Testers

The Digital Ground Resistance Tester Model 6472 is a portable measurement instrument designed to measure Bond Resistance, Ground Resistance (with and without clamps), Soil Resistivity, Earth Coupling, Step & Touch Potential.

When used in combination with the GroundFlex Adapter Model 6474 (factory-supplied product only), Power Transmission Tower and Tower Leg Ground Resistance testing is also available.

The Model 6472 measures from 0.01 to 99.99kΩ and is auto-ranging, automatically seeking out the optimum measurement range, test frequency and test current. The adjustable test frequency (either manual or automatic) from 40 to 5078Hz test voltage provides rejection of high levels of interference, allowing it to be used under difficult conditions such as the presence of high stray currents that normally affect accuracy. Up to 512 test results can be stored in internal memory for later recall to the display or downloaded to a PC using DataView software (included) for Automatic Report Generation, Automatic Fall-of-Potential Plot Generation, Frequency/Resistance Plots, and much more.

Applications

• 3-Point measurements of resistance to ground of ground rods and grids. 3-Point measurements are generally used when the electrode or grid can be easily disconnected.
• 4-Point tests or soil resistivity measurements. Locating areas of the 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 the 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. This test is a DC resistive test using 250mA or more and is used to check the 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.

DataView Graphing & Analysis Software

DataView software provides a convenient way to configure and control ground resistance tests from your computer. Through the use of clear and easy-to-use tabbed dialog boxes, all of Model 6470-B functions can be configured and tests can be initiated.

Results can be displayed in real-time and stored on your PC. Reports may be printed along with the operator’s comments and analysis.
