The Digital Ground Resistance Tester
Model 6470 performs grounding
resistance, soil resistivity, bonding tests
(2- and 4-wire Resistance) and earth
coupling measurements. This direct
reading tester measures from 0.01 to
99.99kΩ, and is auto-ranging,
automatically seeking out the optimum
measurement range test current and test
frequency. Easy-to-use — simply
connect the leads, select the test mode,
Press-to-Measure 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 for analysis
and hard copy reports.
The Model 6470 is Cat IV rated to 50V
and is over voltage protected to greater
than 250V against accidental
connection to live circuits. Live voltage,
if present, is also displayed on screen.
In the event of a system fault, the
Model 6470 can withstand 250V
between any two terminals.
The large LCD is easy-to-read and
indicates grounding electrode
resistance, test voltage, current and
frequency. It also measures individual
test electrode resistance, battery status
and more depending on the
measurement.
Additional features of the Model 6470
include: a heavy-duty field case sealed
against dust and water when closed
(the test button is also sealed against
the elements); NiMH rechargeable
batteries. An external charger powered
Also included, are manual and
automatic test frequency selection from
40 to 513Hz; user selectable Soil
Resistivity test method (Wenner or
Schlumberger); user selectable 2-Wire
or 4-Wire Bond Resistance test
and a Earth coupling test feature.
from 120V/230V 50/60Hz is included.
The Model 6470 can also be powered
and charged from a 12V vehicle battery.
Testing while recharging is allowed.
The Ground Resistance Tester Model
6470 is rugged, easy-to-use and
ideal for maintenance crews and
contractors performing numerous tests.
It exceeds mechanical and safety
specifications for shock, vibration and
drop tests called out in IEC standards.
The adjustable test frequency and
filtering provide for rejection of high
levels of interference, allowing it to be
used under difficult conditions such as
the presence of high stray currents that
normally affect accuracy, and measured
auxiliary rod resistance enables the
user to optimize measurements in
difficult soil environments.

field case – IP54 rated in closed
position
• IEC 61557 parts 4 and 5 compliant
• Includes DataView® software for
data storage, real-time display,
analysis, report generation and
system configuration
Applications
• 3-Point measurements of
resistance to ground of
ground rods and grids. 3-Point
measurements are generally used
when the electrode or grid can be
easily disconnected.
• 4-Point tests or soil resistivity
measurements. Locating areas of
lowest soil resistivity is essential for
achieving an economical grounding
installation.
• Touch and step potential testing
measurements. These tests are
recommended when the ground
cannot be disconnected, where
ground faults are highly likely to
occur, or when the "footprint" of
grounded equipment (the outline of
the part of equipment in contact
with the earth) is comparable to the
size of the ground to be tested.
• 2- or 4-Wire tests for continuity
tests on bonding or on
grounding systems. This test
is a DC resistive test using
250mA or more and is used to
check bonding of all connection
points on the ground system.
• Earth coupling measurement
and display. Used to estimate the
influence of two earth resistance
systems that are not connected to
each other.
Model 6470 quickly checks ground rod resistance with its
Connect – Press – Read approach
