For Fluke 1625-2 Kit – Advanced Geo Earth Ground Tester

The Fluke 1625-2 Kit, is a distinctive earth ground tester that can perform all four types of earth ground measurement. Specifically, the Fluke 1625 Kit 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.

Feature:

The Fluke 1625 Kit 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

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
