Note
• This function works best when the vessel is empty or nearly empty: use it only if there is a
minimum distance of 2 meters from the transducer face to the material.
•
Set Auto False Echo Suppression (2.11.3.2.) and Auto Suppression Range (2.11.3.3.)
(Page 228) during start up, if possible.
• If the vessel contains an agitator, the agitator should be running.
If the device displays a full level, or if the reading fluctuates between a false high level and a
correct level, set Auto False Echo Suppression (2.11.3.2.) to elevate the TVT in this region
and to de-sensitize the receiver from any ‘base noise’ caused by internal transducer
reflections, nozzle echoes, or other vessel false echoes. Set Auto Suppression Range
(2.11.3.3.) (Page 228) and then Auto False Echo Suppression (2.11.3.2.) (detailed
instructions follow Auto Suppression Range 2.11.3.3.) (Page 228).
