29.2.3 Stop conditions
The conditions for canceling the titration are defined under [Stop condi-
tions].
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 meas. value
The titration is canceled when the specified measured value has been
reached since the start of the titration.
The values that are actually measurable may vary from the values specified
here, depending on the hardware. The binding measurement value ranges
can be found in the "Technical specifications" chapter for the control
device used.
