The Fluke 1625 is distinctive earth ground testers 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.

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.

Features:

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