Performing a first time calibration of the roll and pitch
measurements of a door mounted sensor
If you want your sensor to measure the pitch and roll of the trawl doors, you must
calibrate it. You can calibrate a sensor in the relevant
Configurator
dialog box.
Prerequisites
Calibration must be done with the sensor mounted in its installation adapter on the
trawl door(s).
Context
When a sensor is mounted on a trawl door, the pitch and roll measurements may need to
be calibrated. If you do not calibrate your sensors you will not know if the pitch and
roll readings are correct. If existing sensors have been replaced, or new sensors have
been installed, a new calibration is required if the trawl door installation offset values are
not available.
Procedure
1 Place the sensor in the door adapter.
On the port door, the “down element shall face down”. On the starboard door, the
“side” element shall face down.
2 Place the door on a stable surface.
