Personal Greeting

The Fluke 393 FC CAT III 1500 V True-RMS Clamp Meter with iFlex is designed for technicians who work in high voltage dc environments: solar arrays, wind power, electric railways, data centres battery banks for uninterruptible power supplies. The Fluke 393 FC will measure up to 1500 V dc, 1000 V ac, and up to 999.9 A dc or ac through the clamp jaw.  The included iFlex flexible current probe extended ac current measurements up to 2500 amps. This clamp has a thin jaw, giving you access to cables in crowded combiner boxes. Test leads are designed with your work in mind and are also rated to CAT III 1500 V dc.


Other key functions:

  • IP54 rated, ideal for work outdoors on solar arrays and wind power systems 
  • DC power measurement, showing readings in kVA
  • Audio Polarity indicator helps prevent accidental misfires
  • Visual Continuity turns to provide a bright green light in the display, ideal when working in dark and noisy environments
  • Logging and reporting of test results via Fluke Connect software
  • When measuring ac current the included iFlex flexible current probe gives you unparalleled access to cable is tight spaces.  The iFlex probe can be twisted through extremely small spaces and provide accurate current measurements.


The world's first CAT III 1500 V true-RMS clamp meter

  • Measure safely with CAT III 1500 V rated clamp meter
  • Thin jaw for access to cables in crowded combiner boxes
  • Sturdy IP54 rated for outdoor use 
  • Work efficiently with dc power measurement, audio polarity and visual continuity
