Flexible AC Current Probe 2500 A

This Fluke iFlex probe measures alternating current up to 2500 A with a flexible 18 in coil that fits around conductors up to 5.7 in in diameter. It connects to compatible Fluke clamp meters through the dedicated iFlex interface and is rated for CAT IV 600 V and CAT III 1000 V safety environments. Accuracy is specified as ±3 % plus 5 counts at 500 Hz frequency response.

Installation and common issues

The probe plugs directly into the iFlex connector on supported Fluke meters such as the 374, 375, 376 and 381 models. No additional adapters or configuration steps are required for basic AC current measurements. The most frequent issue is attempting to use the probe with meters that lack the iFlex input, which prevents any reading from being captured.

Measurement capacity and limits

The probe comfortably handles AC loads up to its 2500 A rating across the stated 500 Hz bandwidth, making it suitable for heavy industrial conductors and busbars. It does not measure DC current, and accuracy degrades beyond the specified frequency response. The 5.7 in jaw opening sets the physical limit for conductor size, so larger cables or bundled feeds may exceed the probe's reach.

Questions about this item

How can I verify the iFlex probe is reading correctly after connecting it to my Fluke meter?

Clamp the flexible coil around a known AC load and confirm the display shows current within ±3 % + 5 counts of the expected value at up to 500 Hz.

What comes with the iFlex 2500A 18 in probe and what must I supply separately?

The package includes the flexible current probe with Fluke iFlex connector and printed instructions; a compatible Fluke clamp meter (374, 375, 376 or 381) is required but not included.

Which Fluke meter models work with this 2500A 18 in iFlex probe?

The probe is designed for Fluke models 374, 375, 376 and 381; choose the meter that matches your measurement category and feature needs.
