The Fluke 374 is a true-RMS clamp meter that can be used to measure current levels up 600A (AC and DC). By equipping an optional Fluke iFlex probe it is also possible to expand this range further up to 2500A (AC only).
In addition to standard current measurements via the clamp built into this unit the 374 can also be used to measure AC and DC voltage to 600V, resistance to 6000Ω and capacitance levels from 1μF to 1000μF. Since this is a true RMS device, measurements are always as accurate as possible.
A built-in continuity test is also included with this clamp meter. The product is CAT III 1000V and CAT IV 600V safety rated.
Fluke has many different clamp meters in their 300 range - this table outlines the common features that can be found in each.
