4.4.3 Evaluation of minimum and maximum (EVAL MIN/MAX)
For the minimum or maximum measured value the associated volume,
time and temperature are interpolated from the list of measuring points.
The evaluation begins as soon as the slope of the curve exceeds a par-
ticular threshold value.
• Evaluation: In an EVAL MIN/MAX command either the minimum or
the maximum can be evaluated. If you require both values then you
must define a second EVAL MIN/MAX command in the method se-
quence.
• Threshold value: The evaluation 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.
