[Load] can be used to load new racks from a card. In PC Control the
paths for Card 1 and 2 can be defined in the menu File/Preferences.
These may be directories on a hard disk, a network drive or any
removable storage medium. With Touch Control Card 1 or Card 2 can
only be selected when it is actually in the card slot. The new rack has to
be copied necessarily into a subfolder of "Files".
If this structure is not complied with, the new rack will not be found
because the software accesses directly subfolders of "Files".
It is easiest to create your own racks by using the [Copy] command to
copy an existing rack. In this case it is important that the rack name of
the new rack does not already exist. The selected rack code also must
not have been assigned already. The proposed rack code "110000" is
normally used for special racks.
The selected rack can be adapted with [Edit].
• Beaker radius samples: Enter here the actual radius of the sample
beakers at the general sample positions of the rack. This beaker
radius must not be smaller than the "Min. beaker radius" defined
in the device properties of the tower (see p. 60). Before the lift is
moved to the work position, these two values will be compared and,
if necessary, an error message will be displayed.
• Beaker sensor: When a sample position is moved to with the
MOVE command then, the beaker sensor at the Tower or the
Robotic arm will check whether a sample is present or not. If no
beaker sensor has been selected then no check will be made.
• 1. Calibration position gives the rack position of the first
calibration solution for automatic calibration with a USB Sample
Processor (see Section 4.7). If a sample position has been given as
