Description
The 1630-2 FC clamp measures earth ground loop resistances for multi-grounded systems using the dual-clamp jaw. This test technique eliminates the dangerous and time-consuming activity of disconnecting parallel grounds, as well as the process of finding suitable locations for auxiliary test stakes. You can also perform ground tests in places that were previously difficult: inside buildings, on power pylons or anywhere you don't have access to soil to place auxiliary test stakes
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
