Key features

  • Test the grounding components of equipment in hard-to-reach spaces, including areas that are indoors or fully paved and do not permit driving auxiliary test stakes
  • AC Leakage Current Measurement: Identify AC leakage without disconnecting your earth ground stake from the grounding system
  • Rugged: Heavy-duty clamp jaw stays in alignment and calibration on tough jobsites
  • Logging measurement: Saves up to 32,760 measurements in memory

About the 1630-2 FC

The Fluke 1630-2 FC measures earth ground loop resistance on multi-grounded systems with just the clamp, so no auxiliary stakes are needed, even indoors or on paved areas. It also measures AC leakage current without disconnecting the earth ground system.
