The Fluke 345 meter is a clamp-on electrically-powered device that combines a digital power meter, data logger, oscilloscope and clamp meter into a single device. It can be used with motor drives with variable frequencies as well as high efficiency lighting. Another application in which it can be used is loads using switching electronics.
Some of the features the Fluke 345 comes with include a color power meter display, low-pass filter and high EMC immunity. The harmonic spectrum can be analyzed on the display and high frequency noise is removed with the filter. DC current can be measured easily thanks to the Hall Effect design of the 345. Power quality logging is enabled for the long-term with the internal power analyzer memory. Harmonics measurements, correct operation verification, setting up variable frequency drives, etc, are some of the capabilities offered by this meter.
