The individual menu items will not be shown if the option
does not apply. Example: With a=0 the menu items for config-
uring the analogue output does not apply. You can then skip
the description for this item.
The Pressotronik (Pres) main menu is used to configure the
settings for the switching outputs or the Analogue outputs (if
applicable).
The basic device settings can be changed. General settings can
be configured under Basic Settings Advanced Functions (b.EF).
These settings should be configured first, as they affect the
displays and settings for the individual menus. These settings
are e.g. the units used.
The Diagnostic (dia) menu further contains diagnostics op-
tions.
