Fluke 378 FC FieldSense AC/DC TRMS Wireless Clamp with PQ Indicator and iFlex

Overview

The Fluke 378 FC FieldSense clamp meter is a true RMS instrument designed to deliver precise voltage and current readings while prioritizing safety. By leveraging FieldSense technology, measurements can be made without directly touching a live conductor, creating a faster and more confident testing workflow on both simple and complex electrical setups.

To operate, simply clip the black test lead to a grounded reference, place the clamp jaw around the conductor, and read reliable values on the display. The 378 FC also features a dedicated power quality (PQ) indicator that helps highlight conditions related to current, voltage, or power factor, giving technicians a practical view of potential anomalies without extra steps.

Key capabilities at a glance

• True RMS voltage and current measurements captured through the clamp jaw
• FieldSense technology enables faster, safer testing without live-wire contact
• Complete 3-phase voltage and current testing with fewer steps
• Power quality indicator flags potential issues related to current, voltage, or power factor

The 378 FC goes beyond basic readings by combining voltage, current, and power quality data in a single, streamlined workflow. This makes it suitable for routine checks, service calls, or preventative maintenance in both residential and industrial environments.

Real-world use cases

• Field service: quickly verify supply status at outlets, panels, or junctions without exposing yourself to live conductors
• Industrial maintenance: assess motor circuits, feeders, and distribution paths with confidence and efficiency
• Diagnostics and prioritization: use PQ indicators to guide further investigations and repairs

Ergonomics and build quality are designed for daily field work. The 378 FC supports an iFlex flexible current probe for measurements in tight spaces, expanding where you can measure current without removing components. The display is crisp, and the overall device feels sturdy in hand, ready for demanding environments. While the tool provides actionable data, outcomes depend on the system under test and proper setup, so use readings as a strong guide rather than a guaranteed result.

How this helps your workflow

• Non-contact testing reduces arcing risk and exposure to live conductors
• Clear, actionable readouts speed up decision-making on-site
• Fewer steps for 3-phase testing save time during complex inspections
• PQ indicators help prioritize follow-up checks and maintenance planning
