AEMC 6471 GROUND RESISTANCE TESTER

The Ground Resistance Tester Model 6471 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, Soil Resistivity ( Wenner or Schlumberger method) . The Model 6471 measures from 0.01 to 99.99kO and is auto-ranging, automatically seeking out the optimum measurement range, test frequency and test current. 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 Model 6471 is Cat IV rated to 50V and is over voltage protected to more than 250VAC against accidental connection to live circuits. The voltage is also displayed on screen. In the event of a system fault, the Model 6471 can withstand 250VAC.
