Step4 Compass Calibration
Without GPS, please skip this step
Note:
Don’t calibrate your compass where there is strong magnetic interference, such as magnetite, car
park, and steel reinforcement under the ground.
DO NOT carry ferromagnetic materials with you during calibration, such as keys or cell phones.
Compass module cannot work in the polar circle.
Calibration Procedures
1. Quickly switch the control mode switch from Manual Mode to GPS ATTI. Mode and back to
Manual Mode for 6 to 10 times (or from ATTI. Mode to GPS ATTI. Mode and back to ATTI.
Mode), The LED indicator will turn on constantly yellow.
2. Rotate your Multi-rotor around the horizontal axis (about 360
o
) until the LED changes to constant
green, and then go to the next step.
3. Hold your Multi-rotor vertically and rotate it (its nose is downward) around the vertical axis (about
360
o
) until the LED turns off, meaning the calibration is finished.
4. The LED indicator will show whether the calibration was successful or not.
If the calibration was successful, calibration mode will exit automatically.
If the LED keeps flashing quickly Red, the calibration has failed. Switch the control mode
switch one time to cancel the calibration, and then re-start from step 1.
Tips:
1. You don’t need to rotate your multi-rotor on a precise horizontal or vertical surface, but keep at least
45° difference between horizontal and vertical calibration.
2. If you keep having calibration failure, it might suggest that there is very strong magnetic interference
around the GPS & Compass module, please avoid flying in this area.
3. When to do re-calibration
The flight field is changed.
When the multi-rotor mechanical setup has changed:
a) If the GPS/Compass module is re-positioned.
b) If electronic devices are added/removed/ re-positioned (Main Controller, servos, batteries, etc).
c) When the mechanical structure of the multi-rotor is changed.
If the flight direction appears to be shifting (meaning the multi-rotor doesn’t “fly straight”).
The LED indicator often indicates abnormality blinking when the multi-rotor spins. (It is normal for
this to happen only occasionally)
