Specifications
AEMC 4620 2130.43 4-Point Ground Resistance Tester
The 4620 4-Point Ground Resistance Tester performs soil resistivity and ground resistance tests.
The rugged 4620 measures from 0 to 2000 Ohms, is auto ranging so it automatically finds the best measurement range, and is easy to use which makes it ideal for maintenance crews performing numerous tests. It exceeds safety and mechanical specifications for drop tests, vibration, and shock as specified in the IEC standards. The 4620 is engineered to reject very high levels of interference, making it ideal for use under harsh conditions such as high stray currents that adversely affect accuracy.
4620 Features
Measures soil resistivity with the 4-Point testing method
Measures ground resistance with the 2-Point, 3-Point, and Fall of Potential method
Step voltage tests
Touch potential measurements
Auto Ranging
Designed to reject high levels of noise interference
Very easy to operate just connect, press, and read
LED in faceplate alerts the user of fault connections, high auxiliary rod resistance, and high input noise
Battery powered
Rugged rainproof and dust-proof field case
Continuity tests on bonding
Color coded terminals
Applications
The 4620 can be used for the following tests:
3-point measurements of resistance to ground of grids and ground rods. 3-Point measurements are usually utilized when the grid or electrode can easily be disconnected, if there is suspected corrosion, or circumstances where ground faults are unlikely to occur
Soil resistivity measurements or 4-Point tests. Finding areas of lowest soil resistivity is necessary to achieve a feasible grounding installation solution
4-point tests
Soil resistivity measurements
Touch potential measurements (an alternative to 3-point tests in evaluating electrical safety). This test is preferred when the ground cannot be disconnected, where ground faults are very likely to occur, or when the "footprint" of grounded equipment is comparable to the size of the ground to be tested
