2-, 3- and 4-Point Ground Resistance Tester Kit with DataView® Software


  • 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
  • 2- and 4-Wire Bond Resistance/Continuity Measurement (DC Resistance) with automatic polarity reversal
  • Stores up to 512 complete test results in internal memory
  • Optically isolated USB communication included
  • Display with automatic backlight when entering a function
  • Rugged dustproof and rainproof field case - IP53 rated in closed position
  • AC-powered with rechargeable NiMH batteries from wall charger or vehicle power
  • Auto-off power management
