AEMC Ground Tester 4620-150 4-Point Description:

AEMC Ground Tester 4620-150 4-Point Ground Earth Resistance Tester performs ground resistance and soil resistivity tests. This direct reading testers measures from 0 to 2000Ω, and is auto-ranging, so it automatically seeks outs the optimum measurement range.

The Digital Ground Resistance Tester Model 4620 is rugged, easy-to-use and is ideal for maintenance crews performing numerous tests. It exceeds mechanical and safety specifications for shock, vibration and drop tests called out in IEC standards.

It is designed to reject high levels of interference, so it can be used under difficult conditions such as high stray currents that normally affect accuracy.
AEMC Ground Tester 4620-150 4-Point Characteristics:
 
Measures soil resistivity (4-Point) method
 
Measures ground resistance (2- and 3-Point) Fall-of-Potential method
 
Step voltage tests and touch potential measurements
 
Auto-Ranging: automatically selects the optimum range
 
Designed to reject high levels of noise interference
 
Extremely simple to operate: connect - press - read
 
LED on faceplate informs operator of high input noise, high auxiliary rod resistance and fault connections
 
Battery powered
 
Rugged, dustproof and rainproof field case
 
Can also be used for continuity tests on bonding
 
Color-coded terminals
 
Test Kit includes tester, 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.
AEMC Ground Tester 4620-150 4-Point Applications:
 
Three-Point measurements of resistance to ground of ground rods and grids. Three-Point measurements are generally used when the electrode or grid can be easily disconnected, if corrosion is suspected, or where ground faults are unlikely to occur
 
Four-Point tests or soil resistivity measurements. Locating areas of lowest soil resistivity is essential for achieving an economical grounding installation
 
Touch potential measurements, an alternative to 3-Point tests. A recommended test when the ground cannot be disconnected, where ground faults are highly likely, or when the "footprint" of grounded equipment is comparable to the size of ground to be tested
