is shown in the main dialog, but can be edited. A fixed sample size
cannot be entered in the main dialog. You can also define sample size
limits in the method which will be monitored during the determination
sequence (START of the determination and at the end of the
determination) (see Section 3.16.6).
Note!
The sample size limits are not monitored during the input of the
sample data in the main dialog.
3.19.2 Sample data request in the determination sequence
To make sure that the sample data input is not forgotten you can also
request the sample data in the determination sequence with a
REQUEST command. The automatic sample data request in the
determination sequence is essential for back-weighing. In the method
you can define which data (Identification 1 and/or 2, sample size) is to
be requested (see Section 4.13.3).
If the Hold sequence function is activated in a REQUEST command
then the determination sequence will be stopped and must be
continued when the sample data has been entered with [Continue]. If
the Hold sequence function is deactivated then the determination will
continue in the background until the measured data is required for
further processing. The determination will then be holded automatically
and only continued when the sample data has been entered. In this way
you can ensure that the sample data required for calculations carried
out after the titration, measurement etc. is actually available. In this case
the sample data input is also confirmed with [Continue].
If sample size limits have been defined in the method then these will
be monitored when the entry has been confirmed with [Continue] (see
Section 3.16.6). If a fixed sample size has been defined in the method
then the sample size will be shown during the input of the sample data
but cannot be edited (see Section 3.16.6).
