The new Fluke 1623 and 1625
GEO Earth Ground Testers offer
an innovative solution, called
Stakeless testing, to make your
earth ground loop resistance
testing quicker and easier. No
need for a separate earth
ground clamp.
In addition, the Fluke 1625 offers
these advanced features:
Fluke 1623 and 1625
3- and 4-pole Fall of Potential,
earth resistance loop testing
4-pole Soil Resistivity testing
Selective earth ground rod
testing using 1 clamp
Stakeless earth ground rod
testing using 2 clamps
IP56 rated for outdoor use
Rugged carrying case
Automatic Frequency Control
(AFC) - identifies existing
interference and chooses a
measurement frequency to
minimize its effect, providing
more accurate earth ground
value
R* measurement - calculates
earth ground impedance at
55 Hz to more accurately
reflect the earth ground
resistance that a fault-to-
earth ground would see
Adjustable limits - for quicker
testing
GEO Earth Ground Testers
Stakeless testing
The Fluke 1623 and 1625 earth
ground testers are able to measure
earth ground loop resistances using
only clamps. With this test method,
two clamps are placed around the
earth ground rod and each are con-
nected to the tester. No earth ground
stakes are used at all. A known, fixed
voltage is induced by one clamp and
the current is measured using the
second clamp. Then the tester auto-
matically determines the resistance
of the earth ground rod.
bonded earth ground system exists for
This test method only works if a
the building or structure under test, but
most are. If there is only one path to
ground, like at many residential appli-
cations, the Stakeless method will not
provide an acceptable value and the Fall
of Potential test method must be used.
ground rod does not need to be dis-
connected—leaving the bonded earth
ground system intact during test. Gone
are the days of spending time placing
and connecting stakes for each earth
ground rod on your system—a major
time saver. You can also perform earth
ground tests in places you’ve not
considered before: inside buildings,
power pylons, or anywhere you don’t
have access to soil.
With Stakeless testing, the earth
