Fluke 1625-2: Everything You Need To Know – Specifications, Comparisons, Manuals, And Troubleshooting
Fluke 1625-2 Information
The Fluke 1625-2 GEO Earth Ground Tester is a versatile and powerful tool for testing earth ground systems. It can perform all four types of earth ground measurements: 3- and 4-Pole Fall-of-Potential (using stakes), 4-Pole Soil Resistivity testing (using stakes), Selective testing (using 1 clamp and stakes), and Stakeless testing (using 2 clamps only).
The 1625-2 features Automatic Frequency Control (AFC) to identify and minimize the effects of interference, providing more accurate earth ground readings. It also calculates R* measurement, which reflects the earth ground impedance at 55 Hz to more accurately reflect the earth ground resistance that a fault-to-earth ground would see.
The 1625-2 is IP56 rated for outdoor use and comes in a rugged carrying case. It includes two test leads, two test clamps, two ground stakes, a USB cable, and a user manual.
