Dosing parameter

4.6.8
The dosing parameters (dosing speed, filling speed and max. dosing/titration volume) are determined for each
method. This applies to all types of methods such as manual and automatic titration, dosing and Solution
Preparation (Fig. 177 and Fig. 178).

Fig. 178
The dosing speed can be set in % from 1 to 100 %.
100 % is the maximum dosing speed:
Interchangeable unit
The filling speed can be set in terms of seconds from 20 to 240.
The standard setting of this value is 30 seconds.
For diluted aqueous solutions the filling speed can be six to 20 seconds. For non-aqueous solutions the filling
speed should be set to the 30 seconds. In the case of highly viscous solutions such as concentrated sulphuric
acid the filling speed should be further reduced down to 40 - 60 seconds.
Depending on the method type, the (maximum) the living volume or titration volume can be set to 999.999 or
even 9999.999.
