Max. volume

This is the maximum volume of titrant to be added during the titration.
The titration will stop once this volume reaches the entered value.

A burette cannot be refilled during a Continuous IP method.
So, while editing an Continuous IP method, enter a
Max. volume so that you have:
Max. volume - Predose until < burette volume.
An error message is displayed (Max. vol - Predose > Bur. vol)
if this condition is not fulfilled and you cannot start the method.

Enter in:

Edit method > Parameters menu
Edit reagent > Parameters menu

Range available:

From Predose until (in ml) to 1000.0 ml
In Continuous IP:
From Predose until (in ml) up to the burette volume.

Max. vol -
Predose > Bur.
vol

This error message indicates that a burette cannot be refilled during a
Continuous IP method. You cannot run the method.
Press

✓ and edit the method with a Max. volume so that you

have:
Max. volume - Predose until < burette volume.

or install a burette of a sufficient volume.
