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. 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. 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 value. 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. Adjustable limits – for quick test result verification.
