Fluke 1625 GEO Earth Ground Tester Kit
The 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.
Testing Methods
- 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

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.
