(Notes: This parameter is sign sensitive. Before committing the value
ensure the -/+ sign is correctly selected. This menu needs to be operated
by professionals)
Threshold setting is used to set the threshold limit of the effective echo.
The higher the threshold setting is, the higher the echo amplitude
required to trigger the level measurement. In turn, this eliminates small
signal clutter interference. Note that if the modified threshold value is
larger than the effective echo amplitude, no or false measurement might
result. The default range of echo threshold is 8 DB. See
the definition of this parameter.
