The Fluke 1625 GEO Earth Ground 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.
The Fluke 1625 GEO Earth Ground Tester can perform all four types of earth ground measurement:
3- and 4-Pole Fall of Potential – standard earth ground testing using two ground stakes4-Pole Soil Resistivity - using stakesSelective testing – without disconnecting ground rods, a technician can measure ground resistance using a combination of stakes and a clampStakeless testing – innovative solution using only clamps, instead of ground stakes, to measure earth ground loop resistance.
The Fluke 1625 offers these advanced features:Automatic Frequency Control (AFC) – identifies existing interference and chooses a measurement frequency to minimize its effect, providing a more accurate earth ground valueR* measurement – calculates earth ground impedance at 55 Hz to more accurately reflect the earth ground resistance that a fault-to-earth ground would seeAdjustable limits – for quick test result verification
