View graphs and generate reports with Fluke Power Quality Log software

With its easy-to-use interface, the included Power Quality Log software assists you with logger setup, enables you to verify actual measurement values quickly using the online function, and downloads data from the logger to a connected PC operating on standard Windows® operating systems. You can view the logged data in graphical and tabular form, export it to a spreadsheet, or generate a professional report with the Report Writer function.

For root cause analysis, different measurements such as flicker, voltage and THD can be shown in the same time plot, helping to quickly identify the cause of a disturbance.
Statistical summaries like EN50160 and DISDIP table provide a quick, comprehensive summary. The EN50160 overview display provides a simple display of 8 power quality parameters on one dashboard, according to the latest international power quality standard.
Statistical analysis of Voltage and Current harmonics over a given time period. Red bar graphs indicate issues with the grid. Other colors are warnings for pontential future issues. Harmonics can be presented also as time plots.
