Display levels
The display is switched off under normal operation. Approx. 5 minutes after the last time a
key is pressed, the display is deactivated automatically. The flow rate/temperature display
is always updated every 5 sec. The meter has 4 display levels. You can switch between the
display levels using a long push of the button. A short push of the button takes you to the
next display within a level.
Some windows contain several sequences. In these windows, the screen switches to the
next sequence automatically every 2 sec.
