3. Do not shake violently during the use of the product, avoid violent vibration, away from the vibration source (if you can not avoid please install the shock absorber), so as not to affect the product measurement accuracy;
4. Try to avoid a sharp acceleration, arrest, sharp turn angular velocity greater than 300 DEG /s movement during use, so as not to affect the measurement precision of products.
5. After the switch is started, the angular gyro sensor needs to be static 20S, and the initial value of the measuring unit is restored, so as to ensure the measurement precision of the product. If there is no such operation, the product can also be used normally, but can not reach the normal precision standard .
