+
Positive measured value modification, i.e. in the direction of a greater
voltage or greater current.
-
Negative measured value modification, i.e. in the direction of a lesser
voltage or lesser current.
auto
The titration direction is determined automatically from the start mea-
sured value and the set endpoint.
Extraction time
Minimum duration of the titration. The titration will not be stopped during
the extraction time, even if the endpoint has already been reached. The
titration is however stopped if a stop condition is fulfilled during this time
(see Chapter 29.4.4, page 327). The entering of an extraction time is e.g.
recommended with samples that release water slowly or if a Karl Fischer
oven is used.
Input range 0 - 999999 s
Default value 0 s
Temperature
Temperature entered manually. The temperature is being continuously
measured when a temperature sensor is connected and when Temp.
measurement = automatic or continuous is defined (see sensor dialog
of the command).
Input range –20.0 - 150.0 °C
Default value 25.0 °C
Time interval MP
Time interval for entering a measuring point in the measuring point list.
The measuring point list is limited to 1000 measuring points.
Input range 0.1 - 999999.0 s
Default value 2.0 s
29.4.4 Stop conditions
The conditions for canceling the titration are defined under [Stop condi-
tions], if this does not occur automatically. This could be the case when
the endpoint set is not reached or if the stop criterion (see "Stop crite-
rion", page 325) is not fulfilled.
Stop volume
The titration is stopped when the specified volume has been dosed since
the start of the titration. This volume should be adjusted to the size of the
titration vessel in order to prevent the contents from running over.
