Fluke 377 FC, 378 FC Non-Contact Voltage True-rms AC/DC Clamp Meters with iFlex Voltage and current measurements with FieldSense™ technology The Fluke 377 FC and 378 FC true-rms clamp meters use Field - Sense™ technology to make testing faster and safer, all without touching 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 con - ductor 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 (378 FC only) 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. 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 The 378 FC includes a power quality test that provides quick indication of whether an incoming power problem or an equipment problem exists.

Voltage and current measurements with FieldSense™ technology No more hand-written notes or complicated math.

• Complete 3-phase voltage and current tests in 3 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 the 377FC and 378 FC clamp meter:
• The display turns green when a stable Field - Sense measurement is detected.
• Visual Continuity provides a bright green screen for easy detection of continuity in noisy work areas.
• The TPAK magnetic hanging kit, with 9 inch (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.
• The included carrying case holds the clamp, iFlex probe, test leads and the included black grounding clip. 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. Fluke Connect allows measurements to be sent to a smartphone for logging, collaboration and analysis. Fluke Connect pulls all data related to three-phase measurements including phase rotation and presents the full set of data for analysis at a glance. Data gathered by Fluke Connect can pinpoint elusive intermittent faults. Data collected over regular intervals can be used to spot small changes before they grow into major problems.
