Fluke 377FC Non-Contact True RMS AC/DC Clamp Meter Fluke

The Fluke 377 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.

 

Overview

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

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
