Abstract: Airwheel installs aerospace attitude control theory, fuzzy software algorithm and gyroscope system to realize self-balancing. It is also because of the self-balancing ability that attract millions of fans and when they receive the long-expected scooter, the first thing is check the balancing function. The following shows how to calibrate the balance of self-balancing electric scooter, taking X3 single-wheeled electric scooter as an example.

Thanks to the self-balancing ability, when the angle of the scooter bodywork is listing hard, the control system will intelligently starts protective reactions while the motor stops to work automatically to stay away from the hurts that may be caused by the motor running up in high speed. The following shows how to calibrate the balance of self-balancing electric scooter, taking X3 electric unicycle as an example. Also, you are welcomed to visit https://youtu.be/rWuyrcpPo1k to see the more detailed steps.  

X3 electric self-balancing unicycle is the earliest published model in Airwheel family. But it has been the settler of many Airwheel traditions of its self-balancing electric scooters. X3 one wheel scooter takes some beating, compared with scooters of other series. Indeed, it is no doubt that it takes some time to learn to ride X-series smoothly, however, once one learns to ride with ease, riders will swoon over it deeply.

To calibrate the balance, firstly, you need to disassemble as the following pictures show.

Then, unplug the power code, and turn the power button on to release the remaining electricity in the main control panel.  

Thirdly, weld the red-black line and red line (balance calibration lines) in the red quadrangle to connect mainboard as the bottom-right picture shows.

Fourthly, fasten screws in the key parts, and disassemble the X3 again to take out the calibration lines after doing the calibration.

Then, check whether the plane is horizontal before doing the calibration, and lay the X3 on the horizontal fixture to guarantee the tire to hang in the air, without touching the ground.

After making the calibration, lines short-circuiting at both ends, press the power button and loosen the calibration lines. Then X3 enters into learning state.

The seventh step is to disassemble X3 electric unicycle to take out the calibration lines, and assemble again.
