Ground Resistance Tester Model 6472


AEMC® Introduces an Upgrade to Ground Resistance Tester Model 6472

AEMC's Ground Resistance Tester Model 6472 now includes two additional test voltages of 10 and 60 Volts that can be manually selected. This optimizes it's use in sensitive areas and improves its ability to test in poor soil conditions as well as conduct deep soil resistivity testing.

Other features include:

  • Bond/Connection Resistance (2-Pole and 4-Pole Kelvin sensing)
  • Ground Resistance (3-Pole or 4-Pole)
  • Ground Coupling Resistance
  • Selective Resistance
  • Soil Resistivity (Wenner or Schlumberger method)
  • Ground Potential
  • Ground Resistance with 2 clamps (no auxiliary rods)
  • Ground Resistance of Pylons with the GroundFlex® Adapter Model 6474 and GroundFlex® sensors allow the system to measure leakage current and ground resistance of tower legs without disconnecting the overhead ground conductor.


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.

This tester is powered by NiMH rechargeable batteries and can also be powered from a 12V vehicle battery. Testing can still be performed while recharging.

The Model 6472 is over voltage protected to more than 250VAC against accidental connection to live circuits. The voltage is also displayed on screen. In the event of a system fault, the Model 6472 can withstand 250VAC.

This Ground Resistance Tester Model 6472 is also available in 300 and 500ft kits.
