If desired, other user-defined racks can be delivered and defined in the
instrument via PC software. Irregular arrangements of vessel positions
are also possible.
4.5.2 Magnetic code
Every single rack can be identified by a unique magnetic code. Rod
magnets which are attached to the bottom of the rack can be combined
to form a 6-place binary code. The 788 IC Filtration Sample Processor
can then automatically recognize the mounted rack. This is possible
when the rack is positioned in the normal position. When changing a
rack, the 788 IC Filtration Sample Processor should first be re-set to the
normal position by pressing the <RESET> key or <ENDSEQ> and
<ENTER>. This way the save recognition of a rack and therefore the
correct vessel positioning is made possible. An internal position table
containing the unambiguous definition of the turning angles and vessel
positions is assigned to each rack type.
