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
doesn t require the use of earth ground stakes or the disconnection of ground
rods.
Features:
One-button measurement concept
3- and 4-pole earth ground measurement
2-pole resistance measurement AC
Selective testing, no disconnection of ground conductor (1 clamp)
