The Fluke 393 FC CAT III 1500V True-RMS Clamp Meter is the only clamp meter designed to measure 1500V DC systems, making it ideal for checking solar arrays, wind power equipment, electric railways, data centres, and battery banks. To this end, it features a CAT III 1500V safety rating, 1500V CAT III insulated test leads, and can take the following measurements through its thin clamp jaw:

  • DC voltage: up to 1500V
  • AC voltage: up to 1000V
  • AC/DC current: 999.9A

Furthermore, the supplied iFlex flexible current probe extends AC current measurements up to 2500A while providing access to tight spaces as it can be twisted through extremely small spots. The Fluke 393 FC CAT III 1500V True-RMS Clamp Meter’s thin jaw also enables access to cables in crowded combiner boxes.

Additionally, for safe, simple, and speedy working, the Fluke 393 FC CAT III 1500V True-RMS Clamp Meter measures DC power (displayed in kVA) and is equipped with audio polarity and visual continuity indicators. Audio polarity indication prevents accidental miswiring while the visual continuity indicator is particularly useful when working in dark and noisy environments as it turns the Fluke 393 FC CAT III 1500V True-RMS Clamp Meter’s digital display bright green.

Models with Fluke Connect technology offer even more convenience as results can be wirelessly logged to the Fluke Connect App, allowing you to analyse and share results, as well as create reports.

The IP54-rated Fluke 393 FC CAT III 1500V True-RMS Clamp Meter is an ergonomic, easy-to-use, safety-optimised clamp meter ideal for technicians working inside or outside in high voltage DC environments.
