A.4
Auto False Echo Suppression
False echoes can be caused by an obstruction in the beam path (pipes, ladders, chains, and
such). Such false echoes may rise above the default TVT curve.
Auto Suppression Range (2.11.3.3.) (Page 228) allows you to set a distance, and Auto False
Echo Suppression (2.11.3.2.) (Page 227) then instructs the device to ’learn’ where the
obstructions/false echoes are within that distance. The new TVT curve is set above the false
echoes, screening them out.
