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

®

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 live

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 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)
