The dosing speed can be set in % from 1 to 100 %.
100 % is the maximum dosing speed:

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.
The (maximum) the living volume or titration volume can be set to 9999.999.
The following filling options can be set for the dosing mode (Fig. 112):

a verification will be performed each time prior to the next dosing step in order to
determine whether the dosing step can still be made without a filling operation.
Should this prove to be impossible, the first thing to occur is filling, followed by the
dosing step.
«
intelligent after
»
a verification will be performed after the next dosing step to find out whether the next
dosing step can still be made without filling.
