Method type

4.6.1
On the «Method type» you can select whether you wish to perform a manual or automatic titration, a dosage or
whether you wish to prepare a solution.
Fig. 76
The selection of the Method type will have an influence on the further parameterisation of the method
For instance, if you select the dosing mode, neither a selection of a formula nor a change of the automatic
titration mode (KF and dead stop) will be available.

Automatic titration

4.6.2
For an automatic titration, you can select from the following modes:

KF titration

Dead Stop titration
4.6.2.1 KF and Dead stop titration
KF titration is a specific form of Dead-Stop titration.
In normal Dead-Stop titration, titration is to the specified value in µA, which must be maintained for a defined
time. In KF titration, this still occurs, but a specified drift criterion in µg/min must also be met. With KF titration,
a conditioning step is also is preset in order to eliminate any moisture in the titration vessel and the solvent.
The first stage of the Dead-Stop and KF titration consists in the continuous dosing up to a delta value away from
the set end point. The dosing speed can be adjusted. Subsequently, titration is performed with linear step sizes
between the delta value and the end point.
In addition one can also carry out a measurement:
