+
Positive measured value alteration, i.e. in the direction of a higher pH
value, greater voltage or greater current.
–
Negative measured value alteration, i.e. in the direction of a lower pH
value, lesser voltage or lesser current.
auto
The titration direction is determined automatically from the start meas-
ured value and the set endpoint.
Extraction time
Minimum duration of the titration. Titration will not be stopped during the
extraction time, even if the endpoint has already been reached. Titration is
however stopped if a stop condition is fulfilled during this time (see Chap-
ter 7.3.6, page 105). The entry of an extraction time may be advisable,
e.g. for the titration of sparingly soluble samples.
