If you’re dealing with aviation systems measuring key power quality parameters at 400Hz is a must. The Fluke 437-II provides that capability (and measures at 50 and 60Hz too) and is designed for users who need to quickly get to the source of the power quality problem, so they can minimize expensive downtime.
The integrated shipboard power measurement system analyzes according to MIL-STD 1399 to automatically give a full evaluation of voltage, current and power according to the standard. This evaluation makes measurement and analysis as easy as can be. The measurement process and the way the 437-II displays data have been optimized to provide to the most important information as quickly as possible.
