3.4 Manual Operation Manual Operation
By way of introduction, we list here only the basic functions for
manual operation that are necessary to prepare the sample
changer for the processing of a sample series. They can be exe-
cuted with just a few keystrokes.
For further commands and details see chapter 4.4, "Changer
Commands", page 94ff.
Selecting a tower (only with the 2-tower model)
TOWER
SEL ECT
Most of the functions for manual operation are specific and valid
for only one tower at a time. With <SELECT/TOWER> you can
switch between the towers. The tower that is currently active is
indicated by the LEDs TOWER 1 and TOWER 2. The following
commands or keys refer to the tower that is currently active:
MOVE (з, и) , LIFT (й, к, HOME, END), PUMP.
Turning the sample rack / Positioning the samples
Using the <ç> and <è> keys the sample rack can be turned
one position to the left (in the counterclockwise direction) or right
(clockwise). The beaker positions are then directed to the active
lift. Special attention should be given to sample racks whose an-
gle of rotation for the beaker positions does not correspond to the
arrangement of both towers (for example, 16 or 14-place racks,
irregularly arranged rack positions).
8
MOVE With the MOVE command, a particular (sample) beaker can be
placed under the active lift. With <SELECT> the numerical rack
position as well as the predefined current sample (SAMPLE
command) or the special beakers 1-8 can be chosen.
Example:
MOVE : sample <ENTER>
MOVE : spec.1 <ENTER>
MOVE : 5 <ENTER>
Important:
For security reasons turning the sample rack is only possible
when the lift (or both lifts) are in or above the shift position.
