2-, 3- and 4-Point Ground Resistance Tester Kit with DataView® Software–EST6472
• Measures Ground Impedance at frequencies up to 5kHz to test lightning strike protection
• Ground Resistance testing using the 2 clamp method (no auxiliary rods needed) using optional current probes
• Includes DataView® software for data storage, real-time display, analysis, report generation and system configuration
• 3-Point Fall-of-Potential measurement with manual or automatic frequency selection
• Used under difficult conditions such as the presence of high-stray currents that normally affect accuracy
• Automatic report generation including the fall of potential plot
• 4-Point soil resistivity measurement with automatic calculation of Rho and user selection of Wenner or Schlumberger test
method
• 3-Point earth coupling measurement
• Manual and automatic frequency scan from 41 to 5,078Hz for optimum test accuracy in electrically-noisy environments
• Selectable test voltage of 16 or 32V up to 250mA of test current
