PC Control / Touch Control
Only Identification 1 is shown with the title "Charge". The fixed sample
size "10 mL" is shown and cannot be edited.
You can also define the limits for the sample size which will then be
monitored in the determination sequence.
Open the dialog Sample data/Sample size limits and activate
the Monitoring sample size limits checkbox.
Enter a Lower limit and an Upper limit for the sample size.
The limits will not be monitored when the sample size is entered in the
main dialog, but at the START of the determination and at its end, when
an automatic sample data request is made with a REQUEST command
and on recalculating a determination. It does not matter whether the
sample size has been entered in the main dialog "by hand", transmitted
by a balance or barcode reader or entered in the sample data silo.
When monitoring is switched on and the limits for the sample size are
infringed then an entry in the message list for the determination will
be made automatically (see Section 3.18.2).
Activate the Display message checkbox if a message is to be shown
during a determination sequence to indicate that the sample size limits
have been infringed. You then have the choice of continuing the run or
of canceling it. This Message can be provided with a Time out, i.e. it
will vanish automatically when the given time has elapsed and the run
will be continued automatically.
