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.
Features:
• 2- and 4-pole bond resistance and continuity measurement capabilities with automatic polarity reversal for versatile testing
• 3-pole fall-of-potential measurement, ensuring accurate ground resistance readings in varied environments
• 4-pole soil resistivity automatically calculates Rho and allows selection between the Wenner or Schlumberger test methods.
• Manual and automatic frequency scanning from 41 to 513 Hz to achieve optimal test accuracy, even in electrically noisy conditions.
• Selectable test voltage of 16 or 32 V, with up to 250 mA of test current, catering to different testing requirements.
• Can store up to 512 complete tests to facilitate comprehensive data collection and review.
• Includes DataView software for remote setup and operation.
• Rechargeable NiMH batteries can be charged using a wall charger or vehicle power
