Introduction
The Fluke 374 FC/375 FC/376 FC (the Product) measures true-rms ac current and voltage, dc
current and voltage, inrush current, resistance, and capacitance. The 375 FC and 376 FC also
measure frequency and dc millivolts. The detachable iFlex (Flexible Current Probe) that is
included with the 376 FC (optional with the 374 FC and 375 FC) expands the measurement range
to 2500 A ac. The Flexible Current Probe provides increased display flexibility and allows
measurements of awkward sized conductors and improved wire access. The illustrations in this
manual show the 376 FC.
