Using the FieldSense technology, the Fluke 378 FC clamp meter is able to test faster and safer, all without contacting a live conductor. Through the clamp jaw you get accurate voltage and current measurements. With the PQ function the Fluke 378 FC can sense power quality issues automatically.
Includes:
- • 378 FC Non-Contact Voltage True-rms Clamp Meter
- • iFlex flexible current probe (18 inches; 48 cm)
- • TL224 silicone insulated test leads
- • TP175 adjustable length test probes
- • AC285 grounding clip (black, quantity one)
- • TPAK magnetic hanging kit, with 9 inch (23 cm) hanging strap
- • Premium Carrying case
- • Quick reference guide
Set up and sustain preventive maintenance procedures easily using the Fluke Connect® system of wireless test tools and asset management software.
- • Improve your ability to prevent or predict machine failures
- • Make confident decisions with data you can trust and track
- • Access your infrared images from anywhere, anytime with secure cloud storage
- • Connect and collaborate with your team – even when you are in different places
- • Provide more complete information to your maintenance teams
- • Generate work orders that include measurements and infrared images
- • Edit and analyze images; create and send reports from your smartphone directly from the field
