The AEMC 6471 Digital Ground Resistance Tester 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 6471 measures from 0.01 to 99.99kΩ and is auto-ranging, automatically seeking out the optimum measurement range, test frequency and test current.

Product Features:
*Ground Integrity Measurement
*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 (r) and user selection of the Wenner or Schlumberger test method
*3-Point Earth Coupling measurement
*Manual and Automatic frequency scan from 41 to 513Hz for optimum test accuracy in electrically noisy environments
*Selectable test voltage of 16 or 32V up to 250mA of test current
*Auto Power OFF feature
*Automatic recognition of all electrode connections and their resistance value
*Stores up to 512 complete test results in internal memory
*Display with automatic backlight when entering a function
*Optically isolated USB communication cable included
*Rechargeable NiMH batteries from wall charger or vehicle power
*Rugged dustproof and rainproof field case - IP53 rated in closed position
*Grounding standards IEC 61557 parts 4 and 5 compliant
*Includes DataView software for set up, data storage, real-time display, analysis, report generation and system configuration
