Stabilization function
The ST90 system is provided with a built-in motion sensor to provide electronic
stabilization of the sonar beams. It is placed inside the Motor Control Unit. For improved
operational accuracy, an external motion reference unit (MRU) can be used. If the sensor is
malfunctioning the input can be disabled.
How to open
This function is opened from the
Setup
menu.
Description
The
Stabilization
function allows you to enable or disable the input from the motion sensor.
• Select
On
to enable the input.
• Select
Off
to disable the input.
If you disable the input from the sensor, the beams will not be compensated for pitch and
toll movements.
Tip During normal operation, always keep
Stabilization
set to On. This is the default
setting. Turning stabilization off may be helpful if you suspect that the sensor provides you
with bad data, or if you need to troubleshoot the interface. If you turn stabilization off and
this improves the echo presentation you must check your motion sensor.
