Fluke 1620-2 Series Geo Earth Ground Testers
Recommended Accessories
The Fluke 1623-2 and 1625-2 Earth Ground Testers offer data storage and download capabilities via USB port, have a large display and world class accessories that will simplify and speed up testing time These unique earth ground testers that can perform all four types of earth ground measurement: • 3 and 4-Pole Fall-of-Potential (using stakes) • 4-Pole Soil Resistivity testing (using stakes) • Selective testing (using 1 clamp and stakes) • Stakeless testing (using 2 clamps only) • IP56 rated for outdoor use • Professional carrying case • USB data storage and transfer • Two year warranty In addition, the Fluke 1625-2 offers these advanced features: • Automatic Frequency Control (AFC) - identifies existing interference and chooses a measurement frequency to minimise 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
