work position 125 mm
• Because you have already positioned the needle at the desired
height, you can accept the current lift position directly by pressing
. Of course the work position can be entered manually or
the value that has automatically been accepted can be modified
later. Lift positions are given in millimeters (0…125 mm), measured
from the uppermost limit (rest position) of the lift. Consider during
the input of the working position that with sample tubes sealed with
PE caps the work position must be set to 125 mm, since otherwise a
vacuum can develop in the sample tube and the sample will not be
aspirated correctly.
