EMFGraph is a small C# program for the GQ EMF-390 meter.
It visualizes data, downloaded with emf390cli.exe in a graphical form.
For now you can only download, load and view the data. Routines for printing reports will be added in the near future.
Download version 0.9 from here.
You will need emf390cli.exe which is available at GitLab.
And offcourse, check out GQ Electronics for more great measuring units.
