Display dimming

The period of averaging flow values within the range is set here. Maximum value is 29sec. Averaging
is then used for the other outputs as well.

Display backlight

Here, you can set the period during which the display backlight is turned off after the last activation of
a button. Use the and buttons to select the desired settings from menu (permanent, 40sec, 20sec,
