In this
example the code is:
000110
In order to allocate a certain sample rack to a particular application it is
possible to define particular properties or characteristics for up to 16 racks.
This makes sense when an application requires a particular size of vessel,
size of sample series or a particular procedure in order for the method to be
carried out.
The following characteristics can be defined for each rack:
Rack name
The rack name is used for the unambiguous
identification of a rack. The command 'Changer' in the
method run can be used to stipulate the use of a
particular rack. The automatic rack recognition ensures
that the use of an incorrect sample rack is recognized
and that the operator is informed of this.
Beakers
The number of beaker positions is obtained from the rack
table. It does not need to be entered.
Special positions
For the lift stations of a changer tower particular „stopping points“, i.e.
predefined lift positions can be laid down:
Work
The work position is used for fixing the position of the
titrating head (lift), in which e.g. a titration can be carried
out. Depending on the height of the sample beaker the
ideal setting can always be selected for each sample
rack. In manual operation this work position can be
moved to directly by means of the
<PG DN>key.
Shift
The shift position is used to fix the position of the
titrating head (lift) in which the sample rack can be
rotated. If the lift is not at or is above the shift position
then the sample rack cannot be rotated. This is a safety
measure as damage to the sensors caused by rotary
movement of the rack is practically ruled out. A
precondition is the correct setting of the shift position. In
manual operation this shift position can be moved to
directly with the
<PG UP>key.
Rinse
The rinsing position is used to fix the position of the
titrating head (lift) at which the sensors can be rinsed at
the titrating head.
