Description

Earthing or grounding of electrical equipment is essential to maintain safety, protecting lives, as well as prevent damage to equipment. The 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 innovate cord winders make clean up a breeze.

CAT II 300 V

Key features

  • Three-electrode method, Two-electrode method (Simple Measurement)
  • Dramatically faster setup: Comes with improved grounding rods and cord winders
  • Wide measurement range for 0 to 1150 Ω, based on EN standard
  • Switchable measurement frequency to reduce the effects of power supply harmonics
