Stakeless testing, quick ground loop testing (2 clamps)
Measuring frequency 128 Hz

The Fluke 1623 and 1625 are distinctive earth ground testers that can perform all four types of earth ground measurement. Specifically, the Fluke 1623 and 1625 testers are able to measure earth ground loop resistances using only clamps called Stakeless testing. This method doesnt require the use of earth ground stakes or the disconnection of ground rods.

Testing Methods
3- and 4-Pole Fall of Potential standard earth ground testing using two ground stakes
Selective testing without disconnecting ground rods, a technician can measure ground resistance using a combination of stakes and a clamp.
Stakeless testing innovative solution using only clamps, instead of ground stakes, to measure earth ground loop resistance.

Includes:
AA LR6 Batteries
Measuring leads 1.5 m
Connector Cable (for RA 2- pole measurements)
Alligator Clips
