3 Sample Racks
717 Sample Changer, Sample Racks 15
The standard racks provided by Metrohm are already equipped
with a predefined magnetic code for every rack type. If several
racks of the same type are used, the magnet rods can be ar-
ranged differently so that a unique identification of a sample rack
is possible, if this is desired.
Format of a magnetic code (example):
000001 i.e. only one magnet is inserted, bit 0
000101 i.e. two magnets are inserted, bit 0 and 2
63 different combinations are possible. The code 000000 stands
for "no code defined".
