Orientation
Figure 3-28: Orientation
Enable Tilt Compensation
is recommended to set active at all time because then the sensor will automatically
compensate for any tilt.
Enable Fixed Heading
might be used if there is any magnetic disturbance that might interfere with a compass heading
and the instrument has a fix position. Then Fixed Heading (Deg.M) can be used to set the offset between the Sensor
North direction and the Magnetic North.
The upside down orientation setting should always be set the same way as the intended use; if the sensor is intended to
be deployed upward looking, do not tick the
“Enable Upside Down”
. If the sensor is intended to be deployed downward
looking, tick the
“Enable Upside Down”
.
However, the sensor will work even if the orientation setting is defined as the opposite of the used direction; it is able to
sense the orientation itself and corrects the calculated current directions, heading etc. accordingly. NB! The surface
cell and surface reference of columns does not work if the sensor is orientated upside down while running
(forced to be sensor referenced instead). A status flag in the record status output parameter is also set to indicate
that the sensor has been used in the opposite direction to the configured direction.
