Fluke 1625-2 GEO Earth Ground Tester
 
 
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: Allows for quicker testing by setting pass/fail parameters.
 
Versatile Testing: 3- and 4-pole Fall-of-Potential, earth resistance loop testing.
 
Soil Resistivity: 4-pole Soil Resistivity testing capabilities.
 
Selective Testing: Earth ground rod testing using 1 clamp.
 
Stakeless Testing: Earth ground rod testing using 2 clamps.
 
Rugged Build: IP56 rated for outdoor use and includes a rugged carrying case.
 
Data Management: USB data storage and transfer for easy reporting.
