Question?

 

 

The Fluke 1625 is the advanced earth ground tester that performs all four types of earth ground tests and includes features that give quicker and more accurate readings.

 

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.

Key Features

  • Programmable limits, settings
  • Measuring voltage switchable 20/48V
  • Automatic frequency control (AFC) (94, 105, 111, 128 Hz)
  • Earth impedance measurement at 55 Hz
  • Stakeless testing, quick ground loop testing (2 clamps)
  • Selective testing, no disconnection of ground conductor (1 clamp)
  • 2- and 4-pole resistance measurement DC
  • 2-pole resistance measurement AC
  • 4-Pole soil resistivity testing
  • Continuity with buzzer
  • 3- and 4-pole earth ground measurement
