"The Fluke 1625-2 offers data storage and download capabilities via USB port. Its a distinctive earth ground tester that can perform all four types of earth ground measurement.The Earth Ground Tester is able to measure earth ground loop resistances using only clamps. This method does not require the use of earth ground stakes nor the disconnection of ground rods.3- and 4-pole Fall-of-Potential, earth resistance loop testing . 4-pole Soil Resistivity testing . Selective earth ground rod testing using 1 clamp . Stakeless earth ground rod testing using 2 clamps . IP56 rated for outdoor use . Rugged carrying case . USB data storage and transfer. Automatic Frequency Control (AFC), identifies existing interference and chooses a measurement frequency to minimize its effect, providing 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 quicker testingModel Number = 1625Kit Contents = Batteries, Cable Reel x 3, Carrying Case, Earth Ground Stake x 4, Fluke 1625 Tester, Inducing Clamp, Sensing Clamp, Test Lead x 2, User ManualFor Use With = 1625 SeriesCalibrated = RSCAL"
