2.12.1 Compass calibration

PDF p. 37

The compass (magnetometer) has been calibrated when the aircraft leaves the factory, and users usually do not need to calibrate it. PDF p. 37

If the flight application displays a warning alert “Compass needs calibration, please calibrate before flight.”, please follow the steps below to calibrate it. PDF p. 37

Important

PDF p. 37

The compass is very sensitive to electromagnetic interference, which can cause compass errors and a decrease in flight quality. PDF p. 37

Please choose an open outdoor area for calibration. PDF p. 37

Please stay away from strong magnetic field areas or large pieces of metal during calibration, such as magnetic ore, parking lots, construction areas with underground steel bars, near underground or overhead power transmission lines, etc. PDF p. 37

Please do not carry ferromagnetic materials or metal objects with you during calibration, such as mobile phones, watches, etc. PDF p. 37

During the calibration process, please stay away from charged objects and keep the aircraft 1.5 meters above the ground. PDF p. 37

During the calibration process, please do not turn off the power of the aircraft or start the motor. PDF p. 37

2.12.2 IMU calibration

PDF p. 38

The IMU (Inertial Measurement Unit) of the aircraft has been calibrated at the factory, and no user calibration is required under normal conditions. PDF p. 38

If the flight application displays warning alerts such as "Cannot take off due to IMU error. Calibrate IMU first." or "Please calibrate IMU", please follow the steps below to calibrate it. PDF p. 38

Important

PDF p. 38

Follow the prompts on the IMU calibration page in the flight application to position the aircraft and ensure it remains in a stationary state. PDF p. 38

Place the aircraft on a flat surface and refrain from moving, turning off, or restarting the aircraft during the calibration process. PDF p. 39

The gimbal will be inactive during the IMU calibration process. PDF p. 39

Please perform the calibration steps according to the tips shown in the IMU calibration interface of the flight application. PDF p. 40

If the calibration fails, repeat the above steps. PDF p. 40

After the IMU calibration is completed, please re-boot the aircraft. PDF p. 40

2.12.3 Gimbal auto calibration

PDF p. 40

The gimbal is calibrated during the manufacturing of the aircraft and typically does not require user-initiated auto-calibration. PDF p. 40

If the flight application prompts “Please calibrate the gimbal motor”, please follow the steps below to calibrate the gimbal. PDF p. 40
