•  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.
  
  With this test method, two clamps are placed around the earth ground rod and each are connected to the tester. No earth ground stakes are used at all. A known, fixed voltage is induced by one clamp and the current is measured using the second clamp. Then the tester automatically determines the resistance of the earth ground rod.
  
  This test method only works if a bonded earth ground system exists for the building or structure under test, but most are. If there is only one path to ground, like at many residential applications, the Stakeless method will not provide an acceptable value and the Fall of Potential test method must be used.
  
  With Stakeless testing, the earth ground rod does not need to be disconnected— leaving the bonded earth ground system intact during test. Gone are the days of spending time placing and connecting stakes for each earth ground rod on your system—a major time saver. You can also perform earth ground tests in places you’ve not considered before: inside buildings, power pylons, or anywhere you don’t have access to soil.

   

  Features:

  • 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.
  • 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.
  • Warranty - 2 Years
