Measure earth ground loop resistance safely with the Fluke 1630-2 FC Earth Ground Clamp Tester. No stakes required. Ideal for industrial grounding, leakage current testing, and preventative maintenance.

Product Information

he Fluke 1630-2 FC Earth Ground Clamp Tester is an industry-trusted solution for measuring earth ground loop resistance and AC leakage current in multi-grounded systems—without disconnecting grounding conductors. Using a dual-clamp jaw design, it eliminates the need for auxiliary test stakes, reducing risk, saving time, and enabling testing in locations previously considered inaccessible, such as inside buildings, on power pylons, or where soil access is not available.

Designed for demanding industrial environments, the rugged clamp jaw maintains alignment and calibration under daily field use. In addition to earth resistance testing, the Fluke 1630-2 FC accurately measures AC earth leakage current, helping technicians quickly identify grounding and bonding issues without interrupting system operation.

The instrument features automatic data logging, storing up to 32,760 measurements at user-defined intervals for efficient trending and analysis. Adjustable high and low alarm thresholds provide immediate pass/fail indication, while the selectable band-pass filter removes unwanted electrical noise for more accurate leakage current readings.

As part of the Fluke Connect® Wireless System, the 1630-2 FC enables wireless data transfer to a smartphone or tablet. Measurements can be stored in Fluke Connect Cloud, linked to specific assets, and shared with teams in real time—supporting informed maintenance decisions, improved uptime, and traceable compliance reporting.

  • 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
