Fluke 1625-2: Pros And Cons, Common Issues, And Best Places To Purchase
Fluke 1625-2 Information The Fluke 1625-2 GEO Earth Ground Tester is a rugged and versatile instrument 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), and Stakeless testing (using 2 clamps only). It also features Automatic Frequency Control (AFC) to identify existing interference and choose a measurement frequency to minimize its effect, providing more accurate earth ground value. Additionally, the R* measurement calculates earth ground impedance at 55 Hz to more accurately reflect the earth ground resistance that a fault-to earth ground would see.
