Compass Calibration
If the compass module is not used, you can skip this step.
The GPS module has a built-in magnetic field sensor for measuring the geomagnetic field, which is not the same in
different areas. The GPS module will not work unless the compass module has been connected. Make sure the compass
module connection is correct.
Always keep the compass module away from the magnet. If this situation occurs please change the compass module
before flying. Otherwise it may damage the compass module and lead the aircraft to work abnormally or even be out of
control.
Calibrate the compass before the first flight or when flying in a different area.
Make sure to keep away from
ferromagnetic substance and other electronic equipment when calibrating or flying. If you keep having calibration
failure, it might suggest that there is magnetic interference or other ferromagnetic substance, please avoid flying in this
area.
If you have calibration failure or the LED flight indicator blinks red and yellow lights alternately (
), please
connect to the Assistant Software, select the “Tools” tab and follow the tips of the “IMU Calibration” to do operation.
1.
Quickly switch control mode switch from GPS Mode to ATTI. Mode and back
to GPS Mode for 6 to 10 times, The LED flight indicator will turn to constantly
yellow.
2.
Rotate your aircraft around the horizontal axis (about 360
o
) until the LED
flight indicator changes to constant green, and then go to the next step.
3.
Hold your aircraft vertically and rotate it (its nose is downward) around the
vertical axis (about 360
o
) until the LED flight indicator turns off, meaning the
calibration is finished.
4.
If calibration was successful, calibration mode will exit automatically. If the
calibration has failed, the LED flight indicator keeps flashing quickly Red.
Switch the control mode switch one time to cancel the calibration, and then
re-start from step 1.
