Digital, 3-Point, 4-Point, Clamp-on (includes 2-SR182 probes), DataView Software

The Digital Ground Resistance Tester Model 6471 is a portable measurement instrument designed to measure Ground Resistance with 2 clamps (sold separately), 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 99.99k and is auto-ranging, automatically seeking out the optimum measurement range, test frequency and test current.
