Description
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-Point and 4-Point Kelvin sensing),
Ground Resistance (3-Point or 4-Point), Ground Coupling
Resistance, and Selective Ground Resistance, 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, test frequency and test current.
Easy-to-use – Simply connect the leads, select test mode,
press Start and read the results. Up to 512 test results can
be stored in internal memory for recall to the display or
downloaded to a PC via DataView
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
connection to live circuits. The voltage is also displayed on
screen. In the event of a system fault, the Model 6471 can
withstand 250V
Additional features of the Model 6471 include manual
and automatic test frequency selection from 40 to 513Hz,
user selectable 3 or 4-Point Fall of Potential or 4-Point Soil
Resistivity test methods and user selectable 2-Wire or 4-Wire
Bond Resistance test method.
The Model 6471 is powered by 9.6V, 3.5 Ah NiMH
rechargeable batteries. An external recharger powered from
120/230V, 50/60Hz is included and provides for testing while
recharging. The Model 6471 can also be vehicle powered
from an optional 12V battery adapter. (Cat. #2135.42)
