During electrical calibration , it must be in the state of no paddle. The prompt sound of different manufacturers'
electric adjustment may be different. Please refer to the manual of electric adjustment.
Accelerometer Calibration
When our flight control leaves the factory, the acceleration has been calibrated. In general, there is no need to
calibrate it again, but in some specific cases, the acceleration needs to be adjusted to ensure the stability and flight
safety, the calibration method is as follows:
enter into "equipment calibration - collectively" page, click on the "calibration" button;
according to clew, put drone/flight control on horizontal level;
click button, according to clew,put drone/flight control on the left side;
click button, according to clew,put drone/flight control on the right side;
Our Flight Control System User's Manual
click button, according to clew, put drone/flight control head down;
click button, according to clew, put drone/flight control head up;
click button, according to clew, turn over drone/flight control;
When it tells calibration is success, means calibration is end,we can restart flight control.
Horizontal Correction
The horizontal correction function mainly solves the installation error, when the flight control is installed on
the rack, and repairs the horizontal error caused by human installation.Place the Orbiter in horizontal.
In the "Equipment Calibration -- Level" page, click "Horizontal Correction" to complete the correction.
Voltage Correction
Read the real value of the battery through the voltage measurement tool, and write the actual value directly, click
“confirm”.
Magnetic Compass Calibration
Magnetic compass calibration makes aircraft heading more accurate. When flying in different environments and
regions, magnetic compass needs to be recalibrated to ensure flight control adapt local magnetic environment, our
flight control magnetic compass calibrate method is as follows:
fast slide "channel mode" switches above 6 times, when the status of indicator light flashing in red, blue, means
have been into the level of magnetic compass calibration mode;
turn the drone on horizontal and gently rotate 360 °, when green light keeps turned on, means horizontal
calibration is completed;
Put drone head straight down, waiting to twinkle red light and green light cycle, said it enters into vertical
magnetic compass calibration mode;
Again put drone gently rotate 360 °, when indicator light stops flashing, blue lights stay turn on, vertical
calibration is completed.
