Product Highlights
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.
- Now includes two additional test voltages of 10 and 60 Volts that can be manually selected. This optimizes it’s use in sensitive areas and improves its ability to test in poor soil conditions, as well as conduct deep soil resistivity testing.
- 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 513Hz for test accuracy in electrically noisy environments
- Earth coupling testing
- Selectable test voltage 16 or 32V up to 250mA 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
Each Unit Includes
- 2-Point, 3-Point, 4-Point
- Bond Test
- Digital Rechargeable Battery
- Dataview Software
