The AEMC Ground Resistance Tester model 4620 performs Ground Resistance and Soil Resistivity tests. This direct reading tester measures from 0 to 200Ω and is auto-ranging so it automatically seeks out the optimum measurement range. The 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. The model 4620 is also designed to reject high levels of interference, so it can be used under difficult conditions such as high stray currents that normally affect accuracy. The model 4620 is powered by 9.6V NiMH rechargeable batteries and also features a built-in recharge circuit, powered from a 120/230V 50/60Hz line, which allows for continuous testing while the unit is recharging.

Features:

  • Measures Soil Resistivity (4-Point) method
  • Measures Ground Resistance (2-Point 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
  • AC-powered with NiMH rechargeable batteries
  • Rugged, dustproof and rainproof field case
  • Color-coded terminals
  • Includes meter, battery and AC-power cord

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 in circumstances 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 in evaluating electrical safety. This test is recommended when the ground cannot be disconnected, where ground faults are highly likely to occur, or when the "footprint" of grounded equipment is comparable to the size of the ground to be tested.
