5.3.6 Course of a sample series
The following points should be taken into account before starting a series:
• Check whether all sample beakers have been placed on the rack
correctly. It is absolutely necessary that the beaker containing the first
sample of the series is present. Other sample beakers can be added as
the series is being processed.
• After the start of the sample series the necessary storage space is
reserved in the working memory according to the settings under
'Statistics'
. If not sufficient storage space is available the process
will be interrupted.
• During the first determination of the series command sequence defined
in the methods of the OMOVE(…)OMOVE loop will be carried out a single
time.
• In the following determinations in the series the neither the
OMOVE(…)OMOVE
nor the CMOVE(…)CMOVE loops will be carried out
(see below).
• In the last determination in the sample series the CMOVE(…)CMOVE
loop defined in the method will be carried out.
These start and closing sequences are provided specially for sample
changer operation and can be used e.g. for conditioning or regenerating
sensors. For these applications the use of special beakers on the sample
rack is a good idea (see configuration, page 42).

It is not absolutely necessary these start and closing sequences
(OMOVE/CMOVE) are defined at the start or end of a method. However,
please note that the method is processed strictly according to the sequence
of defined command lines.
