7.10 Calculations / Formulas
10 calculation formulas can be defined for each titration or measuring
mode. This is done by selecting the appropriate mode in the method editor
with the cursor and pressing the softkey [* Formula].

• • Formulas which have been entered in the method editor are available for
the following determinations. If existing data are to be recalculated then
the formula editor must be called up in the result window. Modified or
newly added formulas can be recalculated there.
Alterations which have been made in the formula editor of the re-
sult window for recalculations are not automatically incorporated
into the method.
• The variable names for results (Rxx) and intermediate results (Xxx)
should be selected to be unambiguous. The same variable names can
be used several times. The contents of the variable is then overwritten
each time. This must be taken into account when such a variable is to be
used in a calculation. Only the current contents of the variable is avail-
able. Only one version of the variable can be used for statistical pur-
poses.
• If several modes with their own sets of formulas are programmed in one
method then it is possible to access the calculated results and interme-
diate results of the previous modes. However, this does not apply to
system variables (EPx, CM, etc. ) which are created directly by the pre-
vious titration or measurement. If required, these can be stored as inter-
mediate results (Xxx).
• If common variables are used in a formula then these are always the
common variables which were in force at the start of the determination.
In each determination copies of the common variables are laid down lo-
cally and accessed as required. When determination data are stored
these are saved in the same record and are available for recalculations.
• If the values of the common variables are altered in a determination
(Cxx=...) then these new values are available for the first time for the next
determination (global common variable).
