  • Rechargeable NiMH batteries from wall charger or vehicle power

The AEMC model 6471 multi-function ground resistance tester is a portable measurement instrument designed to measure: ground resistance with 2 clamps (no auxiliary rods), bond/connection resistance (2-pole and 4-pole Kelvin sensing), ground resistance (3-pole or 4-pole), ground coupling resistance and selective ground resistance, and soil resistivity (Wenner or Schlumberger method).

The AEMC model 6471 measures from 0.01 to 99.99 kΩ and is autoranging, automatically seeking out the optimum measurement range, test frequency and test current. It's also very easy-to-use. Simply connect the leads, select the test mode, press 'Start' and read the results. up to 512 test results can be stored in internal memory for later recall to the display or downloaded to a PC via DataView software.

The AEMC model 6471 ground resistance tester is CAT IV rated to 50 V and is overvoltage protected to more than 250 V AC against accidental connection to live circuits. The voltage is also displayed on the screen. In the event of a system fault, the model 6471 can withstand 250 V AC.

The AEMC model 6471 multi-function ground resistance tester ships complete with:

  • (2) SR182 current probes
  • NiMH battery pack
  • Optically isolated USB cable
  • DataView software
  • External battery charger
  • AC power cord
  • User manual

The AEMC model 6471 multi-function ground resistance tester is also available in kit form which includes the meter and all accssories above as well as:

  • Two 300 foot color-coded leads on spools
  • Two 100 foot color-coded leads
  • 4 T-shaped auxiliary ground electrodes
  • Set of 5 spaded lugs
  • 100 foot tape measure
  • Carrying bags
