Temperature Ranges; Specifications - Fluke 1623 Datasheet

The most complete testers
The Fluke 1623 and 1625 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)

2 Fluke Corporation 1623 and 1625 GEO Earth Ground Testers
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
or 1625 tester, test leads, 4 earth ground stakes,
3 cable reels with wire, 2 clamps, batteries, and
manual—all inside a rugged Fluke carrying case.
