4.
Hold the drone nose-down and rotate clockwise
about 2~3 turns until the remote controller screen
prompts “Initializing…”.
5.
Place the drone on a level surface for 30 seconds.
When the prompt disappears, power off and restart
the drone.
6.
The compass calibration is complete.
1) Compass calibration needs to be performed outdoors in an open area. 2) Remove
propellers before calibration. 3) Perform the calibration process away for sources of
magnetic fields, such as large metal structures, radio signal towers, power lines or
mobile phones, etc.
Gyroscope Calibration
The gyroscope provides stability data to the flight controller. If the gyroscope is not well
calibrated, the aircraft will tilt to one side when it takes off, and the tilted angle will
increase until the aircraft can no longer fly.
Process gyroscope calibration for the following situations:
•
The drone trembles significantly during hovering in GPS mode.
•
The drone’s tilt range is too large during ascending in ATTI mode.
•
The drone drifts during ascending or descending in GPS mode.
•
The drone has been crashed or subjected to the heavy shaking.
•
The remote controller screen prompts “WARNING Gyroscope error Calibrate
Gyroscope”.
