Damping until

Range from the start of the measurement in which the curve is additionally
damped. This parameter allows to minimize the influence of titration arti-
facts (e.g. spikes), which occur at the beginning of the measurement and
can mistakenly be interpreted as endpoints. The damping functions as a
linear ramp, i.e. its influence is the highest at the beginning and then decrea-
ses linearly to the defined volume.

Range

0.0 ... 50.0 mL

Default value

0.2 mL

Conditions for stopping the titration. If more than one stop condition is in
effect at the same time, then the criterion which is fulfilled first will stop the
titration.

Stop volume

Stops when the given volume has been added after the start of the titration
(including start conditions). The stop volume should be adapted to suit the
sample weight or the titration vessel size.

Range

0.01 ... 50.00 mL

Default value

off

Stop measured value

Stops when the measured value entered for a measuring point has been
reached since the start of the titration. Thereby, the direction of the meas-
urement curve (ascending or descending), which is determined after record-
ing the first 50 measuring points, is taken into account.

Range

0.0 ... 60.0 °C

Default value

Stop time

Stops when the preset time (including start conditions) has elapsed since the
start of the titration.
