Statistics are switched on. The mean value of the titer in mg/ml is automatically saved in the attachment.
It is then used automatically in the sample titration.
The results of the sample titration are calculated in %.
If needed, the unit can be converted into other units of measure, such as ppm.
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.
The following titration parameters can be set for the Dead-Stop and KF titration
