Compass Calibration
Without GPS module, please skip this step. If you use with GPS module, follow step-by-step for calibration.
(1)
DO NOT calibrate your compass where there is magnetic interference, such as magnetite, car
park, and steel reinforcement under the ground.
(2)
DO NOT carry ferromagnetic materials with you during calibration, such as keys or cell phones.
(3)
Compass module CANNOT work in the polar circle.
(4)
Compass Calibration is very important, otherwise the system will work abnormal.
Calibration Procedures
1.
Switch on the transmitter, and then power on autopilot system!
2.
Quickly switch the control mode switch from
GPS Mode
to
Manual Mode
and back to
GPS Mode
(or
from
GPS Mode
to
ATTI. Mode
and back to
GPS Mode
) for more than 5 times, The LED indicator will
turn on constantly yellow so that the aircraft is ready for the calibration.
3.
(Fig.1) Hold your Multi-rotor horizontal and rotate it around the gravitational force line (about 360
o
) until
the LED changes to constant green, and then go to the next step.
4.
(Fig.2)Hold your Multi-rotor vertically and rotate it (
its nose is downward
) around the gravitational force
line (about 360
o
) until the LED turns off, meaning the calibration is finished.
Fig.1 Fig.2
5.
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 2.
1.
When the GPS is abnormal, the Main controller will tell you by the LED blinking Red and Yellow
alternately (
), disable the GPS Module, and automatically enter the aircraft into the
ATTI. Mode.
2.
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.
3.
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.
4.
When to do re-calibration
(1)
The flight field is changed.
(2)
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.
(3)
If the flight direction appears to be shifting (meaning the multi-rotor doesn’t “fly straight”).
(4)
The LED indicator often indicates abnormality blinking when the multi-rotor spins. (It is normal
for this to happen only occasionally)
