What is the advantage of using a flexible current clamp instead of a rigid jaw clamp?

The flexible coil in the i400s wraps around large or awkwardly-positioned conductors without requiring the conductor to fit between fixed jaws, making it practical for measuring high currents in installations where space is very constrained.

Why would I use the i400s with a multimeter or oscilloscope instead of a traditional clamp meter?

The i400s extends the capability of any Fluke meter or scope with a millivolt input; it lets technicians use familiar instruments while measuring 400 A AC current without carrying multiple tools.

What types of high-current applications require the i400s 400 A range?

Facilities maintenance teams use the i400s to verify large motor branch circuits, main service entrance distribution, and industrial equipment feeders where standard 200-400 A clamps are needed but carrying a dedicated meter is impractical.

How does the flexible design help in tight or congested electrical rooms?

Instead of trying to position a clamp meter around a thick cable, the flexible probe wraps around the conductor and maintains contact, giving reliable readings even in cramped cable trays or conduit configurations.

Is the CAT IV 600V / CAT III 1000V rating safer than standard clamp meters?

Yes, the i400s has the highest safety rating of any current clamp available, providing superior protection during measurement on high-voltage systems and high-fault-current installations.

What millivolt-per-amp ratio does the i400s output, and why does it matter?

The probe produces a proportional millivolt output that any compatible meter can read and convert to amperes; knowing the ratio lets you manually calculate current or program your meter or scope for automatic conversion.
