The PGSTAT302F is a special version of the PGSTAT302N which can be switched from the regular 'grounded mode' to so-called 'floating mode'. In grounded mode, the PGSTAT302F can be used with normal electrochemical cells, while in floating mode, the PGSTAT302F can be used with grounded cells or electrochemical cells in which the working electrode is connected to ground (e.g. pipelines, autoclaves, etc.).
