The Fluke 1625-2 offers data storage and download capabilities via USB port. It's a distinctive earth ground tester that can perform all four types of earth ground measurement.The Earth Ground Tester is able to measure earth ground loop resistances using only clamps. This method does not require the use of earth ground stakes nor the disconnection of ground rods.

3- and 4-pole Fall-of-Potential, earth resistance loop testing
4-pole Soil Resistivity testing
Selective earth ground rod testing using 1 clamp
Stakeless earth ground rod testing using 2 clamps
IP56 rated for outdoor use
Rugged carrying case
USB data storage and transfer
Automatic Frequency Control (AFC), identifies existing interference and chooses a measurement frequency to minimize its effect, providing 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 quicker testing

6 x AA LR6 batteries, 2 x measuring leads 1.5 m, 2 x alligator clips, users manual.
