3.2 Manual operation
As an introduction only those basic manual control functions which are
necessary for preparing the sample changer for processing a series of
samples are described here.
Only a few keys are required.
For further commands and details please refer to page 61ff and page 74ff.
Shift sample rack / position samples
The <Í> and <Î> keys can be used to rotate the sample rack one
position to the left (counterclockwise) or right (clockwise).
8
MOVE The MOVE function can be used to position a particular sample vessel on
the oven. Apart from the numerical rack position, <SELECT> can also be
used to enter the position defined as the current sample (SAMPLE com-
mand) or the special beaker 1 to 8.
Example:
MOVE : sample <ENTER>
MOVE : spec.1 <ENTER>
MOVE : 5 <ENTER>
Important:
For safety reasons it is only possible to rotate the rack when the lift is at or
above the shift position height.
Move lift
The <Ï> and <Ð> keys move the lift upwards and downwards respec-
tively. The lowest possible lift position is defined under the configuration
parameter 'max. lift way'.
HOME END
The <HOME> key is used to return the lift to the resting position (0 mm),
i.e. to the upper stop position.
<END> moves the lift to the predefined working position (see pages 65
and 77).
9
LIFT The LIFT function can be used to move the lift to a particular position. As
well as the exact position in mm (0 –100 mm), a previously defined posi-
tion can be selected with <SELECT> (rest pos = 0 mm, working, rinsing,
shift pos, special).
Example:
LIFT : work <ENTER>
LIFT : shift pos <ENTER>
LIFT : 50 mm <ENTER>
