The Ground Resistance Tester Model 6471 is a portable measurement instrument designed to measure Ground Resistance using 2 current clamps (no auxiliary rods). Other test methods provided are: Ground Resistance (3-Pole or 4-Pole), Ground Coupling, Bond Resistance, Selective Ground Resistance and Soil Resistivity (Wenner or Schlumberger method). The Model 6471 measures from 0.01 to 99.99kΩ and is auto-ranging, automatically seeking out the optimum measurement range 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 download 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. Additional features of the 6471 include a heavy-duty field case sealed against dust and water when closed (the test button is also sealed against the elements); manual and automatic test frequency selection from 41 to 513Hz; user selectable 3-Pole Fall-of-Potential or 4-Pole Soil Resistivity test methods and user selectable 2-Pole or 4-Pole Bond Resistance test method. The Model 6471 is rugged, easy-to-use and ideal for maintenance crews performing numerous tests. It exceeds mechanical and safety specifications for shock, vibration and drop tests per IEC standards. The adjustable test frequency provides for rejection of high levels of interference, allowing it to be used under difficult conditions such as high stray currents that normally affect accuracy.

Applications:

• 3-Point measurements of resistance to ground on ground rods and grids
• 4-Point tests of soil resistivity measurements
• Touch and Step potential testing measurements
• 2- or 4-Wire tests for continuity tests on bonding or on grounding systems
• Earth Coupling measurement and display
