AEMC 4630 Ground Resistance Tester, 2000 Ω, rechargeable battery

$2,101.40
AEMC Instruments 4630 Offers

Rugged and easy to use, this ground resistance tester exceeds mechanical and safety specifications for shock, vibration, and drop tests specified in IEC standards. Additionally, this digital tester rejects high levels of interference, making it ideal for use under challenging conditions, such as high stray currents that affect accuracy.

Features

  • Ground integrity measurement
  • Measures soil resistivity (4-point)
  • Measures ground resistance (2- and 3-point) fall-of-potential method
  • Step voltage tests and touch potential measurements
  • Auto-ranging: Automatically selects the optimum resistance range and test current
  • Designed to reject high levels of noise and interference
  • Extremely simple to operate: Connect/press/hold/read
  • LED on the faceplate informs the operator of high input noise, high auxiliary rod resistance, and faulty connections
  • Large easy-to-read backlit display
  • AC powered with rechargeable NiMH battery pack
  • Rugged dustproof and watertight field case
  • Color-coded terminals

Applications

  • Measure ground rod and grid resistance
  • Use in multi-grounded systems without disconnecting the ground under test
  • Measure resistance and continuity of grounding loops around transformer pads and buildings
  • Measure leakage current flowing to the ground or circulating in ground loops
  • Conduct quick field checks
  • Conduct field surveys and retrieve and analyze readings from stored data
  • Measure the earth resistance of the type of single rod or small ground grids often found in remote telecommunication switching stations
  • Measure ground electrode resistance on lightning protection equipment
  • Measure the earth electrode resistance of equipment in recreational areas, especially public swimming pools
  • Test electrode resistance of installed ground rods and grids at new construction sites before utility power is supplied
  • Test earth electrode resistance of grounded towers and counterpoises at cellular phone remote installations and power transmission towers
  • Three-point measurement of large grounding grids, counterpoises, ground mats, and grounded equipment
  • Locate areas of lowest soil resistivity which is essential for achieving an economical grounding installation
