Fluke GEO Earth Ground Tester 1620 Series

The Fluke 1623 and 1625 are distinctive earth ground testers that can perform all four types of earth ground measurement. Specifically, the Fluke 1623 and 1625 testers are able to measure earth ground loop resistances using only clamps – called Stakeless testing. This method doesn’t require the use of earth ground stakes or the disconnection of ground rods. FLUKE 1623 FEATURES One-button measurement concept 3- and 4-pole earth ground measurement 4-pole soil resistivity testing Selective testing, no disconnection of ground conductor (1 clamp) Stakeless testing, quick ground loop testing (2 clamps) Measuring frequency 128 Hz 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 (AF
