Fluke 378FC OffersUses Field-Sense™ technology to make testing faster and safer, all without touching a live conductor, and provides accurate voltage and current measurements through the clamp jaw. Easily clip the black test lead to any electrical ground, put the clamp jaw around the conductor, and see reliable, accurate voltage and current values on the display.
Features
Measure voltage and current with your clamp jaw
Faster, safer testing all without touching a live wire using FieldSense™ technology
Complete three-phase voltage and current tests in three quick steps
Power quality indicator shows whether a problem is in the equipment or the power line
This clamp meter includes a unique PQ function that senses power quality issues automatically. When making FieldSense measurements, it 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.
Voltage and current measurements with FieldSense™ technology
No more hand-written notes or complicated math.
Complete 3-phase voltage and current tests in three easy steps
Full set of phase-to-ground and phase-to-phase values calculated
Displayed on your smart phone and saved to the cloud via Fluke Connect software
Phase rotation calculated and shown on the Fluke Connect software
Measure extremely high current with iFlex™ probe
Use the included iFlex flexible current probe to measure ac current as high as 2500 A. The iFlex probe provides access to large conductors in tight spaces.
Easy to see, easy to use with included tools
Your job will get easier when you use this clamp meter:
The display turns green when a stable FieldSense measurement is detected
Visual Continuity provides a bright green screen for easy detection of continuity in noisy work areas
The magnetic hanging kit, with 9″ (23 cm) hanging strap, lets you hang your clamp wherever you need: to a steel cabinet door; around a pipe; on a nail or screw head
Record, analyze, share results with Fluke Connect™ software
With Fluke Connect software you can remotely log, trend and monitor measurements to pinpoint intermittent faults. Fluke Connect also allows
you to gather data as the basis for a preventive maintenance program.

Webinar: EVSE Safety Maintenance with Fluke
In recent years, more people are opting for greener solutions to minimize environmental damage, which has led to an increased demand for environmentally safe solutions such as electric vehicles. Naturally, this has led to an increase in the installation of EV charging stations, but also the risks for technicians. In 2020, there were 126 fatal and 2200 non-fatal electrical injuries. Many of these are caused when technicians are exposed to hazardous voltage and arc faults that could cause shock and fire hazards due to a lack of understanding of proper EVSE installation and maintenance. Considering that EVSEs have a high rate of failure, estimated at 30 to 50% (SAE), reliability is essential when building EV infrastructure and gaining user acceptance.
