AEMC 6472 Kit-300ft Ground Resistance Tester Kit, 2-Clamp, 4-Point, 300ft
Product Description
The Digital Ground Resistance Tester Model 6472 is a portable measurement instrument designed to measure Bond Resistance, Ground Resistance (with and without clamps), Soil Resistivity, Earth Coupling, Step & Touch Potential.
When used in combination with the GroundFlex® Adapter Model 6474 (factory supplied product only), Power Transmission Tower and Tower Leg Ground Resistance testing is also available.
Overview
- 4-Pole (4-Point) Fall-of-Potential measurement for very low resistance measurements with manual or automatic frequency selection and automatic lead compensation
 - 3-Point Fall-of-Potential measurement
 - 3-Point earth coupling measurement
 - Manual or automatic frequency scan from 40 to 513 Hz for test accuracy in electrically noisy environments
 - Earth coupling testing
 - Selectable test voltage 16 or 32 V up to 250 mA test current
 - 4-Point soil resistivity measurement with automatic calculation of Rho and user selection of Wenner or Schlumberger test method
 - 2- and 4-Wire DC resistance measurement (Bond testing) with automatic polarity reversal
 - Ground Resistance with 2 clamps (no auxiliary rods)
 - Ground Resistance of Pylons with the GroundFlex® Adapter Model 6474 and GroundFlex® sensors allow the system to measure leakage current and ground resistance of tower legs without disconnecting the overhead ground conductor
 - Includes DataView® software for data storage, real-time display, analysis, report generation and system configuration
 - Auto-off power management
 - Automatic recognition of all electrode connections and their resistance value
 - Stores up to 512 complete test results in internal memory
 - Optically isolated USB communication
 - Rechargeable NiMH batteries from wall charger or vehicle power
 - Rugged dustproof and rainproof field
