Fluke 381 376 374 375 and 373 and iFlex clamp meters
By Anthony Capkun
Fluke Corp. introduced a family of clamp meters that, it says, is designed to “meet every requirement for testing and maintaining electrical systems, industrial equipment and controls, and commercial and industrial HVAC equipment”. The 381 remote display True-rms AC/DC features a detachable display. The 376 is designed for testing large industrial motors and other high-current applications (the 376 and 381 ship with the iFlex flexible current probe). The 375 is designed for use with common motors and drives below 600A. The Fluke 374 is good for security systems, basic motors and UPSs. The Fluke 373 is a general purpose clamp meter. The Fluke iFlex flexible current probes expand the measurement range of compatible Fluke meters to 2500 Aac; the large coil reaches around large conductors and fits between tightly-packed cables. A 6-ft cord allows measurement at a distance for easier viewing. The Fluke 381 is a full-featured clamp meter with an important extra: users can remove the detachable wireless display for more flexibility, convenience and safety.
