calculations. If a result of the variable TITER is assigned in a
calculation then the titer of the "new" titrant will also be overwritten.
Note!
An alteration of the calibration data under System/Sensors (see
Section 3.9.4) cannot be taken into account in a recalculation. A
change of the sensor in a method for a titration or measurement also
has no influence on the measured data.
The fact that a determination has been recalculated is shown under
More determination data/Properties (see Section 3.18.4). The user
who was logged in when the recalculation was carried out will also be
documented together with the time of the recalculation.
A method may be altered so much, e. g. by the insertion of additional
titration commands, that it is no longer possible to recalculate the
determination.
Recalculating loaded determinations:
When a loaded determination is recalculated, the titrant data and the
common variables stored together with the determination are used. If
you want to recalculate the result with a corrected common variable or
a corrected titer then you must alter the corresponding values in the
dialog Results/More determination data under Local common
variables or View data/Titrant data.
Note!
With loaded determinations it is assumed that they have been carried
out a long time ago and that the titrant data and common variables
of the system no longer coincide with those of the determination. This
is the reason why the most important titrant data of the titrants used
and the list of common variables (local common variables) are stored
together with each determination.
If a result is assigned to the variable TITER or to a common variable
then the variables that are currently valid in the system will only be
overwritten after a confirmation.
If you subsequently alter the titrant for a titration in the method then this
alteration cannot be taken into account in the recalculation.
When loaded determinations are recalculated no assignments in the
result silo are carried out.
