Fluke 1630-2

Fluke 1630-2 FC – Overview

The Fluke 1630-2 FC is a stakeless earth ground clamp that enables accurate ground loop resistance and AC leakage current measurements without disconnecting ground systems or driving auxiliary stakes. Ideal for indoor, paved, or crowded areas, it includes a heavy-duty clamp jaw, large memory capacity, and rugged construction for job-site reliability. Wireless connectivity via Fluke Connect allows logging and review on mobile devices.
