Fluke 1623-2

and 1625-2

GEO Earth Ground Testers

The new Fluke 1623-2 and

1625-2 GEO Earth Ground

Testers offer data storage

and download capabilities

via USB port. World class

accessories will simplify

and speed up testing time.

Product features:

•

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

•

Professional carrying case

•

USB data storage and transfer

In addition, the Fluke 1625-2

offers these advanced features:

•

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

Stakeless testing

The Fluke 1623-2 and 1625-2

earth ground testers are able to

measure earth ground loop resis-

tances using only clamps. With

this test method, two clamps are

placed around the earth ground

rod and each are connected 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

automatically determines the

resistance of the earth ground rod.

This test method only works

if a bonded earth ground system

exists for the building or structure

under test, but most are. If there

is only one path to ground, like at

many residential applications, the

Stakeless method will not provide

an acceptable value and the Fall

of Potential test method must

be used.

With Stakeless testing, the

earth ground rod does not need

to be disconnected—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.

The most complete testers

The Fluke 1623-2 and 1625-2

are distinctive earth ground

testers that can perform all

four types of earth ground

measurement:

•

3- and 4-Pole Fall of Potential

(using stakes)

•

4-Pole Soil Resistivity testing

(using stakes)

•

Selective testing (using 1 clamp

and stakes)

•

Stakeless testing (using 2

clamps only)

The testers are also easy to

use. For each test,

the testers inform you which

stakes or clamps need to be

connected and the large rotary

switch can be used even with a

gloved hand.

The complete model kit comes

with the 1623-2 or 1625-2

tester, test leads, 4 earth ground

stakes, 3 cable reels with wire,

2 clamps, batteries, and manual—

all inside a professional Fluke

carrying case.
