WARNING: If the FFU flow sensor is being used for a media other than water, the “Basic Trim” function
must be carried out via the device display during commissioning when the device is filled with fluid.
The medium should not be flowing during the adjustment, since this affects the operation of the
function.

5.2 Display and menu
FFU is available with a display for displaying current measured values as well as for setting applica-
tion-specific parameters. The four pushbuttons on the membrane keyboard can be used to navigate
through the menu and carry out settings. Pressing the “Set” button will return you to the main menu.
The main menu contains a number of submenus for selection. The arrow buttons are used to naviga-
te through the menu. To select a menu item, press the “Set” button again. To input limit values, such
as the value for “Analog output - Max. range”, you should select the desired settings using the arrow
button. The input value will be saved when the “Set” button is pressed. To return to the menu, press
the “Esc” button. You will need to enter a password to make any changes to the parameters via the
display menu. This ensures that only authorized personnel can make changes to the device parame-
ters. The menu password on delivery is
