5.7.3 Sending the sample size from a balance
If the sample size is sent directly from the balance, then it will always be
entered in a new line at the end of the sample table. It does not matter
which line is selected or whether the sample table is even opened. In the
above example, the sample size is entered in line 5.
NOTE
If you would like to enter the sample size in a particular line, then you
must open the corresponding editing dialog (i.e. the Sample data dia-
log is displayed).
If the editing dialog for the sample size is opened, then the sent value
will be ignored.
5.8 Carrying out a determination
The sample size can be entered in the following ways when a determina-
tion is carried out:
￭ Enter manually on the instrument
￭ Send automatically from a connected balance. Consult the user manual
for the balance for this purpose.
The following instructions describe how to enter the sample size on the
877 Titrino plus.

consumption of 10...90 % of the cylinder volume will result.
