Earthing or grounding of electrical equipment is essential to maintain safety, protect lives, as well as prevent damage to equipment. The Tester FT3151 Analog EarthTester uses the AC phase differential system to measure earthing resistance, which assures that accurate measurements are unaffected by earth voltage and auxiliary earthing resistance. New innovative cord winders make clean-up a breeze.
