Canceling the Ringing
On NBTE V2 echograms, there is a ringing coming from the transducer, that appears as
a red line on top of the echogram. You can cancel it.
Before you begin
• To correctly configure the ringing, the sensor needs to be in a large water tank at a depth of at
least 5 meters, or in air, with a space of at least 1.20 meters in front of the Down or Up sounder.
• The sensor is connected to Mosa2.
About this task
Ringing is an oscillation of the signal coming from the sensor transducer. At shallow depth, it can
be confused with the bottom, so it is recommended to deactivate it.
