Fluke 378 FC True RMS AC/DC Clamp Meter with iFlex

What is the 378 FC Clamp Meter?

The Fluke 378 FC True RMS AC/DC Clamp Meter with iFlex is designed for industrial electricians, electrical maintenance engineers and technicians who need fast and accurate troubleshooting on electrical installations and three-phase systems. Fluke FieldSense technology enables simultaneous AC voltage and current measurements through the clamp jaw without contacting a live conductor, helping simplify testing in demanding environments.

 

Advanced Current and Three-Phase Testing

The 378 FC measures AC/DC current up to 999.9 A through the clamp jaw, while the included i2500-18 iFlex flexible current probe extends AC measurements to 2500 A. Its power quality indicator automatically identifies issues associated with current, voltage and power factor while Fluke Connect enables remote logging, monitoring and sharing of measurements. Frequency, resistance, capacitance and 1000 V AC/DC voltage measurement provide further flexibility for electrical fault finding.

 

How Does the Fluke 378 FC Stand Out in Everyday Use?

The combination of FieldSense non-contact voltage measurement, True RMS accuracy and iFlex makes the 378 FC particularly useful when working on crowded panels and large conductors. It can also complete three-phase voltage and current testing in three steps with phase-to-ground and phase-to-phase values calculated for easier troubleshooting.
