Performing a dosing
Pressing the [GO] key causes the dosing to run automatically. The sample
data is requested first. The calculated target volume is displayed. The dos-
ing is started after the [GO] key has been pressed once again.
The dosing can be canceled with the [FILL] key. The dosing cylinder is fil-
led automatically.
