The Digital Ground Resistance Tester
Model 6470 performs grounding resistance, earth coupling
measurement, soil resistivity and bonding tests. This direct
reading tester measures from 0.01 to 99,000Ω, 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.

- 3-Point Fall-of-Potential measurement.
- 3-Point earth coupling measurement.
- Manual or automatic frequency scan
from 40 to 513Hz for test accuracy in electrically noisy
environments.
- Earth coupling testing.
- Selectable test voltage 16 or 32V up
to 250mA test current.
- 4-Point soil resistivity measurement
with automatic calculation of Rho and user selection of Wenner
or Schlumberger test method.
-
2- and 4-Wire DC resistance measurement (Bond testing) with
automatic polarity reversal.

|
- Auto-off power management.
- Automatic recognition of all electrode connections
and their resistance value.
- Stores up to 512 complete test results in internal
memory.
- Optically isolated USB communication.
- Remote set up and operation of all measurements
using DataView® software supplied.
- Rechargeable NiMH batteries from wall charger or
vehicle power.
- Rugged dustproof and rainproof field.
- Includes DataView® software.
-
3-Point measurements of resistance to ground of ground rods and grids.
3-Point measurements are used when 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 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. 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.
