Figure 7-3. Example 2: Surface Threshold is Too Low
By adjusting the surface threshold, the product surface is properly detected, as illustrated in
Figure 7-4:
Figure 7-4. Echo Curve after Surface Threshold was Adjusted
To adjust the amplitude thresholds, see “Using the Echo Curve Analyzer” on page 137.
In the Echo Curve Analyzer in RRM, the amplitude threshold points can easily be dragged to the
desired values.
