the Sample Processor.

quences and method parameters.

Lift operation and sample positioning keys
With the < > and < > keys the lift of the currently active tower can
be moved up and down respectively. The lowest possible lift position
is defined by the configuration parameter 'max. stroke path'.
In the editing mode the arrow keys < > and < > are used
for navigation in the particular menu or submenu.
HOME END
With the <HOME> key the lift of the currently active tower is returned
to the rest position (0 mm), i.e. to the uppermost stop.
<END> moves the lift to the predefined working position (see p. 61).
In the editing mode the <HOME> and <END> keys move to
the first and last line of the menu or submenu respectively.
NEXT PREV
With the < NEXT> and < PREV> keys the sample rack can be
rotated forward or backward by one position. The beaker positions
depend on the active lift. If necessary, the lift (or both lifts) are auto-
matically raised to the shifting position. When the rack position has
been reached a robotic arm which may be mounted will automatically
be directed to the corresponding rack position.
In the editing mode the arrow keys < > and < > are
used for navigation in a menu line.
TOWER
SELECT
Most functions for manual operation apply specifically to a single
tower. With the 2-tower models the <SELECT/TOWER> key can be
used to switch between the towers. The currently active tower is indi-
cated by the TOWER 1 or TOWER 2 LED. The following commands
or keys refer to the active tower: MOVE, < >, < > , LIFT, < >,
< >, <HOME>, <END> and <PUMP>.
During data input the <SELECT> key is used to select a pre-
defined entry from a selection list.
