AEMC Instruments 6472 KIT 150FT

6472Kit-150ft Multi-Function Ground Resistance Testers

The Model 6472 is available in complete kit form, which includes the 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

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


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.
