Aemc 6470 kit ground resistance tester 150 ft
"Your One Stop Source for Sales & Calibration of Test & Measurement Equipiment"
*AEMC 6470 300 ft Ground Resistance Tester Kit*
The Model 6470 300 ft kit 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 measurer and carrying bag.
* 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
* 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
* 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
* 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.
