AEMC Instruments 6472 KIT 500FT Details

AEMC Instruments 6472 KIT 500FT

6472Kit-500ft Multi-Function Ground Resistance Testers

The Model 6472 is available in complete kit form, which includes the instrument, two 500 ft color-coded leads on spools (red and blue), two 100 ft color-coded leads (green and black), one 30 ft lead (green), four 14.5" T-shaped auxiliary ground electrodes, one set of five spaded lugs, 100 ft tape measurer and carrying bag.
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.

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

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

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

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.
