Fluke 1630-2 FC Earth Ground Clamp

The Fluke 1630-2 FC Earth Ground Clamp provides a fast, reliable, and stake-free method of measuring earth ground loop resistance and AC leakage current. By using a dual-clamp jaw design, this tester eliminates the need to disconnect grounding connections or drive auxiliary stakes, enabling measurements in previously challenging locations, such as buildings, substations, power pylons, and paved environments.

With its integrated logging capability, the Fluke 1630-2 FC can store up to 32,760 measurements and automatically record readings at predefined intervals, allowing technicians to analyze performance trends over time. It also includes high/low alarm thresholds for faster decision-making and a band-pass filter that removes unwanted noise from AC leakage current readings, ensuring accuracy in demanding electrical environments.

The Fluke Connect® wireless system integration allows you to save, store, and share measurements directly to the cloud using your smartphone or tablet. This enables remote monitoring, historical data comparison, and collaboration with your team through the ShareLive™ video calling feature.

Designed for tough industrial environments, the clamp’s heavy-duty jaw stays aligned and calibrated under rugged usage. With its CAT IV 600V / CAT III 1000V safety rating, the Fluke 1630-2 FC ensures operator safety while providing precise, dependable results for troubleshooting, preventive maintenance, and safety compliance verification.
