FLUKE 378 NON-CONTACT VOLTAGE TRUE-RMS AC/DC CLAMP METER WITH IFLEX

Voltage and current measurements with FieldSense™ technology The Fluke 378 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 clamp meter includes a unique PQ function that senses power quality issues automatically. When making FieldSense measurements, the 378 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. Complete 3-phase measurements in quick, easy steps Complete 3-phase voltage and current tests in 3 easy steps Full set of phase-to-ground and phase-to-phase values calculated and shown on the meter No more hand-written notes or complicated math.
