Titration to preset end-point.
The reagent addition is con-
trolled such that a preset
measured value is adhered to
as accurately as possible.
The dosing function is con-
trolled such that a nominal
measured value is adhered to
as accurately as possible. The
nominal measured value fol-
lows a linear ramp.
Volume that has been dis-
pensed up to the endpoint
(EPX in ml).
Evaluation of

rates dV/dt in the set time
windows and the mean
rate over the entire meas-
uring point list.
•
volumes associated with a
preset time (fix V).
•
times associated with a
preset fraction of the total
volume (fix time).
The total volume (C41) and the
time needed for dosing (C42)
can be used for calculation.
•
For rapid, quantitative
determinations in analyti-
cal chemistry. Require-
ment: EP of the titration
reaction is known and
does not change during a
determination series.

be avoided.
