28.4.2 Minimum and maximum evaluation (EVAL MIN/MAX)
For the minimum or maximum measured value the associated volume,
time and temperature are interpolated from the measuring point list. The
evaluation begins as soon as the slope of the curve exceeds a particular
threshold value.

Evaluation
Selection whether the minimum or the maximum of the titration curve is
being evaluated. With a command either the minimum or the maximum
can be evaluated. If both values are needed, a second command has to be
defined in the method.
Selection Minimum | Maximum
Default value Maximum
Threshold value
The evaluation of the minimum or maximum begins as soon as the slope
of the curve exceeds the set threshold value. Use a lower threshold value
if the minimum or maximum is not found.
Measuring mode Ipol:
Input range 1.0 - 2,000.0
Default value 25.0
With titrations the unit is mV/mL, with measure-
ments mV/s.
