345

The ideal troubleshooting tool for modern
electrical loads

The Fluke 345 measures a wide range of
electrical parameters for troubleshooting
power disturbances in single- and
three-phase electrical loads. With a
bright color display to see waveforms
and trends, a low-pass  lter to remove
high frequency noise, and a high EMC
immunity design, the Fluke 345 is ideal
for measurements on switching loads
such as variable speed drives, electronic
lighting and UPS systems.
