Fluke i3000s Flex-24 AC Current Probe 3-3000A measurement tool

SKU CH-SBVF-FAR1D

Flexible AC current probe measuring 3 to 3000 A with 6.5 in jaw and BNC output for oscilloscopes or analysers

  • Measures 3 to 3000 A AC for high-current diagnostics
  • Flexible 6.5 in jaw wraps around large 24 in conductors
  • Three output ranges 100 10 1 mV/A match scopes and analysers
  • 10 Hz to 50 kHz bandwidth captures harmonics and transients
  • CAT III 600 V safety rating protects operator and equipment

AC current probe for oscilloscopes and analysers

The Fluke i3000s Flex-24 measures AC current from 3 to 3000 A and connects to oscilloscopes, power quality analysers or DMMs through a BNC connector. It is intended for technicians who need non-invasive current readings on large conductors up to 6.5 in diameter. The probe provides three selectable output sensitivities of 100, 10 and 1 mV per ampere.

Flexible coil simplifies access to tight spaces

The 36 in flexible coil wraps around bus bars or cable bundles where rigid jaws cannot fit, and the 165 mm jaw capacity accommodates large conductors. Installation requires only clamping the coil around a single conductor and selecting the appropriate range on the measuring instrument. Errors usually occur when the coil encircles multiple conductors or when the probe is used outside its 10 Hz to 50 kHz frequency response.

Measurement limited to AC within specified bandwidth

The probe measures AC only and cannot capture DC or transient components outside the 10 Hz to 50 kHz range. Accuracy is rated at ±2 percent of range under CAT III 600 V conditions. Buyers needing DC current measurement or higher frequency response should consider a different probe topology.

Questions about this item

How can I verify the i3000s Flex-24 is measuring correctly after connecting it?

Apply a known AC current within the 3 to 3000 A range and confirm the BNC output reads 100, 10 or 1 mV per ampere with the stated ±2 % accuracy.

What accessories come with the probe and what must I supply separately?

The package includes the flexible probe with 36 in length, 6.5 in jaw capacity and printed instructions; you must provide an oscilloscope, power quality analyser or DMM with a BNC input.

Which output sensitivity setting — 100, 10 or 1 mV/A — should I select for my application?

Choose 100 mV/A for low-current detail, 10 mV/A for general use up to several hundred amps, or 1 mV/A when measuring near the 3000 A maximum to avoid over-ranging your instrument.
