10 Ground Resistance Tester Model 6471
CHAPTER 2
PRODUCT FEATURES
2.1 Description
The Ground Resistance Tester Model 6471 is a portable measurement instrument
designed to measure:
• Ground Resistance with 2 clamps (no auxiliary rods needed)
• Bond/Connection Resistance (2-Pole and 4-Pole Kelvin sensing)
• Ground Resistance (3-Pole or 4-Pole)
• Ground Coupling Resistance
• Selective Ground Resistance
• Soil Resistivity (Wenner or Schlumberger method)
The Model 6471 measures from 0.01 to 99.99k
Ω 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 large LCD is easy-to-read and indicates ground electrode resistance, test
voltage, current and frequency as well as individual electrode resistance, battery
status and more.
The Model 6471 is CAT IV rated to 50V and is over voltage protected to more than
250V
AC 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 250V
AC.
Additional features of the Model 6471 include a heavy-duty eld 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;
4-Pole Soil Resistivity test methods and user selectable 2-Pole or 4-Pole Bond
Resistance test method.
The Model 6471 is powered by 9.6V, 3.5 Ah NiMH rechargeable batteries. An ex-
ternal recharger powered from 120/230V, 50/60Hz is included and provides for
testing while recharging.
The Ground Resistance Tester Model 6471 is rugged, easy-to-use and ideal for
maintenance crews performing numerous tests. It exceeds mechanical and safety
specications 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 difcult conditions such as high stray currents that affect accuracy
