ed echo indications, e.g. structural noise from the test
object.
The height in % indicates the minimum height that the
echoes must attain in order for them to be displayed on
the screen at all. The reject setting cannot be higher
than 80 %.

caution as it may of course happen that you
suppress echoes from flaws as well. Many
test specifications expressly forbid using the
reject function.
