AEMC 6471 KIT-300 FT – Ground Resistance Tester Kit, 300ft w/Probes

• Ground Resistance testing using the 2 clamp method (no auxiliary rods needed)
• 2- and 4-Point Bond Resistance/Continuity measurement (DC Resistance) with automatic polarity reversal
• 3-Point Fall-of-Potential measurement with manual or automatic frequency selection
• 4-Point Soil Resistivity measurement with automatic calculation of Rho (ρ ) and user selection of the Wenner or Schlumberger test method
• 3-Point Earth Coupling measurement

The Ground Resistance Tester Model 6471 is a portable measurement instrument designed to measure Ground Resistance with 2 clamps (no auxiliary rods), Bond/Connection Resistance (2-Pole and 4-Pole Kelvin sensing), Ground Resistance (3-Pole or 4-Pole), Ground Coupling Resistance, and Selective Ground Resistance, Soil Resistivity (Wenner or Schlumberger method). The Model 6471 measures from 0.01 to 99.99kΩ and is auto-ranging, automatically seeking out the optimum measurement range, test frequency, and test current.

Easy-to-use – Simply connect the leads, select the test mode, press Start and read the results. Up to 512 test results can be stored in internal memory for later recall to the display or downloaded to a PC via DataView software.

The Model 6471 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 the screen. In the event of a system fault, the Model 6471 can withstand 250VAC.

Additional features of the Model 6471 include a heavy-duty field case sealed against dust and water when closed (the test button is also sealed against the elements); manual and automatic test frequency selection from 41 to 513Hz; user-selectable 3-Pole Fall of Potential or 4-Pole Soil Resistivity test methods and user-selectable 2-Pole or 4-Pole Bond Resistance test method.

The Ground Resistance Tester Model 6471 is rugged, easy-to-use, and ideal for maintenance crews performing numerous tests. It exceeds mechanical and safety specifications for shock, vibration, and drop tests per IEC standards. The adjustable test frequency provides for rejection of high levels of interference, allowing it to be used under difficult conditions such as high stray currents that affect accuracy.
