The Fluke 1625 is a distinctive earth ground tester that can perform all four types of earth ground measurement.
Specifically, the Fluke 1625 tester is 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.
3- and 4-Pole Fall of Potential – standard earth ground testing using two ground stakes
4-Pole Soil Resistivity testing – determine soil resistivity using four 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
