5.2 Transport System Offset
The offset values are unique for each instrument and are stored in the PHERAstar FS chipset (EEPROM)
before shipment. No further actions are needed. However, wrong definitions of a microplate format can lead
to cross-talk.
Increased cross-talk and drift (in a 1536-well plate with same fluorescein concentration) is
an indication of incorrect or inaccurate dimensions of the microplate definition. Contact
BMG LABTECH service personnel for procedures.

for procedures
The PHERAstar FS has an automatic plate carrier offset determination which uses two small dots for
positioning determination (figure 34). For more details, please contact BMG LABTECH service personnel as
the determination should be carried out only by trained personnel.
