2.7.1 Turning the sample rack / Positioning the samples
NEXT PREV
With the < NEXT> and < PREV> keys the sample rack
can be rotated forward or backward by one position.
< /NEXT> moves the next sample position (SAMPLE+1) to
the tower. < /PREV> moves the previous sample position
(SAMPLE-1) to the tower.

Position vessel /
Turn rack
With the MOVE command rack positions are moved to, i.e. the
turntable rotates until the sample rack is positioned so that the
selected rack position is placed under the needle. With <SE-
LECT> the numerical rack position as well as the predefined
current sample (SAMPLE command) or the special beakers 1-
16 can be chosen. Furthermore, with the robotic arm external
position (not on the rack) can be accessed. More details about
the MOVE command you can find in section 2.4.1.
For security reasons turning the sample rack is only possible
when the lift is in or above the shift position. The lift is auto-
matically raised, if its current position is lower than the prede-
fined shift position.
2.7.2 Moving the lift
The keys < > and < > allow upward and downward move-
ment of the lift. The lowest possible lift position is defined by the
configuration parameter
' max. stroke path '
.
HOME END
The <HOME> key runs the lift to the rest position (0 mm), i.e. to
the upper limit.
<END> runs the lift to the predefined work position (see sec-
tion 2.2.3).
