Fluke 378 FC True-rms Non-Contact Voltage AC/DC Clamp Meter with PO Indicator, iflex

Why we love the Fluke 378FC

Loaded with technology! - FieldSense, Fluke Connect & Power Quality Indicator

The first of its kind non-contact voltage clamp meters, powered by revolutionary FieldSense technology from Fluke. The dual display shows voltage and current readings simultaneously as both measurements are taken via the clamp jaw. Visual Continuity also provides a bright green screen for easy detection of continuity in noisy work areas.

The Fluke 378FC Non-Contact Voltage True-rms AC/DC Clamp Meter (with iFlex) is the more advanced version of the 377FC, the main difference is that this model includes a unique Power Quality Indicator function that senses power quality issues automatically and will indicate whether equipment or power line is faulty.

When making FieldSense measurements, the 378 FC will detect and display power quality issues relating to current, voltage, power factor or any combination of the three. Now you can quickly determine if an upstream supply problem exists or if there is a downstream equipment problem, allowing you to take corrective action quickly.

The iFlex flexible current probe allows you to measure AC current as high as 2500A, its design means you can assess large conductors in difficult to reach spaces with ease.

No more hand-written notes or complicated maths

Complete 3-phase voltage and current tests in 3 easy steps
Full set of phase-to-ground and phase-to-phase values calculated
Displayed on your smartphone and saved to the cloud via Fluke Connect software
Phase rotation calculated and shown on the Fluke Connect software

Record, analyze, share results with Fluke Connect® software

Communicate with a smartphone/ tablet with the Fluke Connect App downloaded. Via this app, users can view and save measurements, monitor, log and trend data, and calculate parameters such as Phase Rotation. Fluke Connect and the Fluke Connect App are particularly useful when attempting to identify intermittent faults.

The Fluke Connect (FC) capability allows you to:

Save measurements to your phone and the Fluke Cloud, for comparison of readings over time
remotely log, trend and monitor measurements to pinpoint intermittent faults
Gather data as the basis for a preventive maintenance program
