More About this Item
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 99.99kÙ 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.
