Apart from viewing Realtime data as values or a graph in the Diagnostics or Web application , you can also log these values to a file (Diagnostic App) or the internal memory card of a GS-911WiFi device if using the Web application.
These values gets saved as .CSV files which you can download to your phone or computer. You can import the logged Realtime values in .CSV file format in LiveGraph, Microsoft Excel, LibreOffice Calc or similar applications.
If a spreadsheet application opens the file with the whole data line in one cell, then you need to modify the "List Separator" to be a semicolon ";" instead of a comma "," .This can normally be selected within the application itself or under the Regional settings of your Operating system (e.g. Windows).
