6470-B Kit-150ft Multi-Function Ground Resistance Testers

The Model 6470-B is also available in complete kit form, which includes instrument, two 150 ft color-coded leads on spools (red and blue), one 30 ft lead (green), two 14.5" T-shaped auxiliary ground electrodes, one set of five spaded lugs, 100 ft tape measure and carrying bag.



Features:

  • 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
  • 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
  • Remote set up and operation of all measurements using DataView software supplied
  • Rechargeable NiMH batteries from wall charger or vehicle power
  • Rugged dustproof and rainproof field
  • Includes DataView software


    Applications
    # 3-Point measurements of resistance to ground of ground rods and grids. 3-Point measurements are used when electrode or grid can be easily disconnected.
    # 4-Point tests or soil resistivity measurements. Locating areas of lowest soil resistivity is essential for achieving an economical grounding installation.
    # Touch and step potential testing measurements. These tests are recommended when the ground cannot be disconnected, where ground faults are highly likely to occur, or when the �footprint� of grounded equipment (the outline of the part of equipment in contact with earth) is comparable to the size of the ground to be tested.
    # 2- or 4-Wire tests for continuity tests on bonding or on grounding systems. Test is a DC resistive test using 250mA or more and is used to check bonding of all connection points on the ground system.
    # Earth coupling measurement and display. Used to estimate the influence of two earth resistance systems that are not connected to each other.
