(see Chapter 29.3.4, page 315). The entry of an extraction time may be
advisable, e.g. for the titration of sparingly soluble samples.
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). This value is used for temperature correction in pH
measurements.
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
29.3.4 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 313) 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.
Input range 0.00000 - 9999.99 mL
Default value 100,000 mL
Selection off
Stop time
The titration is stopped when the specified time has elapsed following the
termination of the start conditions.
Input range 1 - 999999 s
Selection off
Default value off
Filling rate
Rate at which the dosing cylinder is filled.
