Trawl Explorer | V2 | Sensor Configuration
About this task
The transducer (yellow part) can be installed in two different positions, with a different angle
of 90°. When the down sounder points to the ground, the A1 board inside the sensor can be in a
vertical or horizontal position depending on the transducer orientation.
Usually, for V1 versions of sensors, the standard orientation is horizontal and for V2 and V3 it is
vertical. If the selected orientation is not the standard one for your version, this has no effect on
the correct functioning as long as you select the correct orientation.
Procedure
1.
Place the sensor with the down sounder (circle or A on transducer) toward the ground.
2.
Click the tab Pitch and Roll.
3.
From Select Orientation, click Apply.
The orientation is selected according to the A1 board orientation.
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 Mosa.
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.
