Detail AEMC 6472 GROUND RESISTANCE TESTER
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.
The Model 6472 measures from 0.01 to 99.99k© and is auto-ranging, automatically seeking out the optimum measurement range, test frequency and test current. The adjustable test frequency ( either manual or automatic) from 40 to 5078Hz test voltage provides rejection of high levels of interference, allowing it to be used under difficult conditions such as the presence of high stray currents that normally affect accuracy.
Features:
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
Automatic recognition of all electrode connections and their resistance value
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
Auto-off power management
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
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
