Fluke 378 FC/E Pinça amperimétrica True-RMS AC/DC com iFlex e FieldSense, 999,9 A, 1000 V, Fluke Connect 5225723

The Fluke 378 FC/E stands apart from conventional clamp meters by combining True-RMS accuracy with FieldSense non-contact voltage and current measurement, plus iFlex flexible current probe support for conductors up to 2500 A AC. This model is engineered for technicians who need reliable readings in crowded panels or tight spaces without breaking the circuit.

Highlights

• True-RMS AC/DC clamp meter with 999.9 A jaw capacity
• FieldSense technology measures voltage and current without test leads
• Includes iFlex current probe for AC measurements up to 2500 A
• Power quality indicator shows voltage, current, power factor, and THD
• Fluke Connect compatible for wireless data logging and sharing
• Safety rated CAT III 1000 V / CAT IV 600 V

In daily use

The 378 FC/E simplifies troubleshooting by letting you check voltage and current simultaneously with FieldSense—just clamp around a conductor and read both values on the backlit display. The iFlex probe extends reach into tight cable bundles, while the low-pass filter ensures stable readings on variable frequency drives. Inrush current capture helps identify motor start-up issues, and the power quality indicator flags potential harmonics or power factor problems before they cause downtime.
