Setting Selection/values Explanation
Method
The rising side of the echo is evaluated for
the measured value determination. One of
two methods can be selected for this.
Rel. threshold The measured value is equivalent to the
point where the intensity of the echo
reaches the adjusted relative threshold.
The value relates to the maximum of the
echo intensity (100 %):
Maximum gradient The measured value is equivalent to the
point with the maximum gradient:
