- Model: Non-Contact Voltage True-rms AC/DC Clamp Meter with iFlex
Product overview: Fluke 378 FC
Non-Contact Voltage True-rms AC/DC Clamp Meter with iFlex
Voltage and current
measurements with FieldSense™ technology
The Fluke 378 FC true-rms clamp meter uses FieldSense™
technology to make testing faster and safer, all without contacting a live
conductor. You get accurate voltage and current measurements through the clamp
jaw. Simply 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.
Power quality indicator shows whether a problem is in the
equipment or the power line
The 378 FC clamp meter includes a unique PQ function that
senses power quality issues automatically. 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.
Key Features
Measure voltage and current with your clamp jaw
Faster, safer testing - all without touching a live wire -
using FieldSense™ technology
Power quality indicator shows whether equipment or power
line is faulty
Complete 3-phase voltage and current tests in 3 quick steps
