The Fluke 1630-2 FC is a stakeless earth ground clamp designed for fast, safe earth ground loop resistance and AC leakage current testing in both indoor and outdoor environments. It allows technicians to 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. The instrument identifies ground loop resistance without the need to disconnect and then reconnect the earth electrode from the system, keeping the protected system continuously online during measurement.

Applications named for this instrument include measurement of earth ground loop resistance for multi-grounded systems, AC leakage current identification for system troubleshooting, and ground testing in locations such as inside buildings, on power pylons, or anywhere soil access for auxiliary test stakes is unavailable. The stakeless measurement technique eliminates the time-consuming activity of disconnecting parallel grounds and the process of finding suitable locations for auxiliary test stakes. The selectable band-pass filter function removes unwanted noise from the AC leakage current measurement, which is useful in electrically noisy industrial settings.

ValueTronics is an authorized Fluke distributor that has supplied test and measurement equipment to electrical, industrial, and field service professionals for over three decades. Each new 1630-2 FC unit is stocked, inspected, and shipped from our 20,000 sq ft secure warehouse at 1675 Cambridge Drive, Elgin, Illinois, where our in-house team verifies instrument readiness before it reaches your facility. This direct stocking and verification model is how we keep delivery timelines short and accountability local, rather than passing orders through to drop-shippers.

## Brand Heritage

Fluke Corporation has manufactured precision electrical test instruments under the Fluke name continuously since 1948. Fluke became a subsidiary of Danaher Corporation in 1998, and in 2016 transferred to Fortive Corporation when Fortive was spun off from Danaher. The Fluke brand and its product lines, including the earth ground clamp portfolio, have remained continuous through these corporate transitions.
