Ground Resistance Tester

The Model 6472 measures from 0.01 to 99.99kW 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. The Model 6472 is Cat IV rated to 50V and 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.
AEMC’s New Ground Resistance Tester Model 6472 is a portable measurement instrument designed to measure:

• Bond/Connection Resistance (2-Pole and 4-Pole Kelvin sensing)
• Ground Resistance (3-Pole)
• Ground Resistance (4-Pole - 10x more sensitive than 3-Pole)
• Ground Coupling Resistance
• Selective Ground Resistance using a Current Probe
• Soil Resistivity (Wenner or Schlumberger method)
• Ground Potential
• Ground Resistance with 2 Clamps (no auxiliary rods)
• Ground Resistance of Power Transmission Tower Legs when used with the GroundFlex™ Adapter
• Model 6474 and GroundFlex™ Sensors
