6.9 Selection menu Span (Adjustment)
If you use a sensor for the filling level measurement where
the 20 mA point does not match the tank height (e.g.
pressure sensors), make a sensor adjustment in the "Span"
menu. You see a submenu with the two options
• Change and
• Reset.
Select a menu item with the UP [
Ç
] and DOWN [
È
] keys and
confirm your selection with RETURN [
] .
You need a password to change the tank height for the UM-O and
UM-O Ex equipment versions (overfill prevention).
