The Digital Ground Resistance Tester Model 6470-B is a portable measurement instrument designed to measure Ground Resistance, Soil Resistivity (two methods – Wenner and Schlumberger), Bonding Resistance (DC Resistance 2-Wire and 4-Wire Kelvin sensing) and Earth Coupling resistance. This direct reading tester measures from 0.01 to 99.99kO and is auto-ranging, automatically seeking out the optimum measurement range and test current. » More
6470-B Kit - 150 ft. Multi-Function Ground Resistance Tester
The Model 6470-B is also available in complete kit form, which includes instrument, two 150 ft color-coded leads on spools (red and blue), one 30 ft lead (green), two 14.5" T-shaped auxiliary ground electrodes, one set of five spaded lugs, 100 ft tape measure and carrying bag.
Applications
- Earth coupling measurement and display. Used to estimate the influence of two earth resistance systems that are not connected to each other.
- 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.
- 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.
- 4-Point tests or soil resistivity measurements. Locating areas of lowest soil resistivity is essential for achieving an economical grounding installation.
- 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.
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 in your PC. Reports may be printed along with the operator’s comments and analysis.
