The Fluke 1630-2FC is a stake-free ground loop resistance clamp meter. Based on dual-coil induction technology, it measures total loop resistance of full parallel grounding grids simply by clamping the ground conductor, without power cut or excavation for auxiliary ground stakes, drastically cutting field inspection working hours. The 32 mm wide jaw fits flat steel and multi-strand thick ground cables, with simultaneous ground leakage current measurement to double-check hidden grounding hazards. Bluetooth connects to Fluke Connect mobile APP for on-site recording, photo attachment and paperless grounding acceptance reports. IP40 dustproof, 1 m drop-resistant design, long runtime powered by 2 AA batteries, fully compliant with IEC 61557-5 ground safety test standard. An efficient grounding inspection tool for PV plants, industrial factories and lightning protection projects,
