Command for Set endpoint titrations.
Principle
With this command titrations to one or two preset endpoints are carried
out. The termination of the titration at the endpoint is either drift-control-
led or after a waiting period. The volume that has been added when the
endpoint is reached gives the calculable reagent consumption.
Reagent addition takes place in three phases during the titration:
￭ Initial dosing
During this phase the dosing rate increases continuously. It starts with
the Min. rate and increases to the Max. rate.
￭ Continuous dosing
The dosing continues to be carried out at the Max. rate until the
Control range is reached.
￭ Control range
Dosing is finely controlled in this range. Shortly before the endpoint is
reached, dosing is carried out only at the Min. rate (Control range).
