Ejecting
DOS: XX : eject mL Empty the Dosino burette.
The contents of the burette is ejected completely via the dosing port. This
can be redefined as desired (see Dosing).
Adjust
DOS: XX : adjust mL Compensate the play
The mechanical play between the dosing piston and the spindle is com-
pensated. This command is important for exact pipetting when small vol-
umes are aspired into the pipetting tube and ejected again. First, the con-
tent of the cylinder is ejected completely (eject), then before the solution is
aspired, the piston is adjusted (adjust).
Level
DOS: XX : level mL Compensate the play
The mechanical play between the dosing piston and the spindle is com-
pensated after the cock has been turned into the dosing position. The
dosing port can be redefined as desired (see Dosing). This command is
executed to increase the precision.
