Fluke 1625 GEO Earth Ground Tester
Fluke 1625 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
-
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
Fluke 1625 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.
