For here you can download a PDF version of the manual as well as the actual help file.

If you want to download the help file, save it in to the same folder as PowerLog Capture runs from (usually c:\program files\p squared\Powerlog Capture v4 but this is a config option so please check). Once it is there, the Help Contents option should appear on the Help Menu to allow access to Help from inside the product. (N.B. you must be on the latest version of PowerLog Capture v4 to take advantage of this).

Any comments or feedback is welcome.
