Fluke 377 FC True-RMS AC/DC Clamp Meter with iFlex

The Fluke 378 FC with Fieldsense technology can measure voltage and current without contacting a live conductor. Simply attached the black test lead to any electrical ground and place the tip of the clamp jaw around the conductor. Moreover, both the current and voltage measurements are displayed on the same screen.

Power Quality Indicator.

The Fluke 378 FC really is unique thanks to its built in power quality indictor that shows automatically whether a problem is in the equipment or power line. When taking a FieldSense measurement, the Fluke 378 FC will detect and display on screen power quality issues relating to current, voltage and / or power factor. This helps the user quickly identify if a problem exists upstream, of if it is in fact an issue with the equipment.

Fluke 378 FC applications

  • Check for the presence of voltage
  • Measuring individual voltages
  • Measuring resistances up to 60 kΩ
  • Checking circuit loading at panel boards
  • Generator / Motor / Chiller maintenance and troubleshooting
  • Installation of HVAC motor and compressor
  • Determining intermittent faults in assembly machinery
  • Identifying efficiency in motors and drives

Measure more with iFlex

The Fluke 378 FC comes with the 18 inch iFlex included. The iFlex is a thin and flexible probe, ideal for clamping around conductors in crowded or hard to reach areas. Furthermore, the iFlex can measure high current up to 2500A, as opposed to the standard fixed jaw which can measure up to 1000A.

Fast and easy 3 phase measurement

  • 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
  • Values are displayed on your smart phone and saved to the cloud via Fluke Connect
  • Phase rotation auto-calculated and shown on the Fluke Connect software
  • No more hand-written notes or complicated math.

True RMS voltage and current measurement

Electrical noise can cause inaccurate readings on instrument. The Fluke 378 FC uses True RMS measurement to give reliable, accurate results every time. The 378 FC uses True RMS measurement for both current and voltage functions.
