The data generated by the meter can be viewed in the display loop with
system information (e.g. flow rate, volume, date, due date, medium tem
-
perature). The loops are numbered from 01 to 09.
The optical button located on the front panel enables scrolling the display
loops.
To save battery lifetime, the meter switches automatically to power save
mode after 4 minutes of inactivity. The display is awakened again by
pressing the optical button.
After awakening, the display shows first a screen check (i.e. all symbols
in the display are briefly switched on and off) and then the total volume.
This remains for at least 10 seconds on the display (also when the optical
button is pressed). Afterwards the display loop can be switched with the
help of the optical button.
