4.5 Calculations
In the method sequence result calculations can be defined with the
CALC command. A method can contain a maximum of nine CALC
commands each with nine result calculations. The CALC commands
also contain instructions for statistical calculations, titer assignments,
storing common variables and storing results in the result silo. Limits
can also be defined for the results. A range of calculable variables
(raw data from the determination, previously calculated results and sys-
tem-specific variables) is available for the calculations. Results which
are calculated in the method sequence can be entered as variables for
parameters.
During titrating or measuring a calculated result can be displayed live
with the CALC LIVE command. The current volume or measured value
respectively is calculated for this purpose. This is helpful e. g. for KF ti-
trations in order to follow the water content during the titration.
4.5.1 CALC command
Up to nine result calculations can be defined in a CALC command. The
results will be calculated in the sequence which is defined by the num-
bering of the result variables: R1...R9.
In the list of results you can use [Edit] to enter the equations and pa-
rameters for the result calculation and delete the selected result with
[Delete] .
You can insert a new result calculation in the list with [New]. The list
with Metrohm result templates is opened.
