916 Ti-Touch
The following method commands are executed once again with the
[Recalculate] function:
￭ DET and MET titrations:
The potentiometric evaluation will be carried out again.
￭ EVAL commands:
All evaluations are carried out again. You can also insert new evalua-
tions retroactively.
￭ CALC command:
All calculations are carried out again. You can also define new calcula-
tions retroactively.
If you subsequently modify the titrant in a method, then the variables
TITER and CONC of the "new" titrant will be used. If a result is assigned
to the variable TITER in a calculation, then the titer of the "new" titrant
will also be overwritten.
NOTE
If you modify the calibration data of the sensor used in the System /
Sensors dialog, these modifications will not be taken into account.
Changing the sensor in the method also has no influence on the mea-
sured data.
If a determination has been recalculated, this will be documented in the
determination properties (see Chapter 23.4, page 220).
Recalculation/reevaluation of loaded determinations
With loaded determinations, it is assumed that they were carried out a
long time ago and that the titrant data and common variables of the
system no longer correspond to those of the determination. This is why
the most important titrant data of the titrants used and the list of com-
mon variables are stored with each determination. This data will be used if
you recalculate a loaded determination. If you wish to recalculate the
result with a corrected common variable or with a corrected titer, you
must therefore modify the respective values in the More determination
data / Local common variables or More determination data / View
data dialog.
If a result is assigned to the variable TITER or to a common variable, then
the titers or common variables which are currently valid in the system will
not be overwritten until after a query has been confirmed.
If you modify the titrant retroactively in the method, this will not be taken
into account.
The recalculated results of loaded determinations are not saved in the
result table.
