The 378 FC Fluke non-contact voltage true rms AC/DC clamp meter with iFlex uses field sense technology to make testing faster and safer, all without touching a live conductor. Its power quality indicator shows whether a problem is in the equipment or the power line and the unique PQ function senses power quality issues automatically.
When making field sense measurements, the 378 FC clamp meter will detect and display power quality issues, relating to current, voltage, power factor or any combination of the three. It can quickly determine if an upstream supply problem exists, or if there is a downstream equipment problem. It uses the included iFlex flexible current probe to measure ac current as high as 2500 A.
Measurements are displayed on your smart phone and saved to the cloud via Fluke connect software. Its visual continuity provides a bright green screen for easy detection of continuity in noisy work areas. Designed to meet the demands of professionals in the field, the 378 FC clamp meter redefines precision, reliability, and connectivity.
