What calibration procedures are performed on the MEMS IMU before shipment? And What are the quality control steps taken during IMU production to ensure sensor consistency?

The calibration of IMU performance indicators such as Zero bias, scale factor, misalignment error, and temperature compensation were mainly carried out. The temperature compensation range is the operating temperature range of gyroscope and accelerometer, and the compensation range varies depending on the product.

To ensure the stability and reliability of sensor performance. Zero bias repeatability testing to ensure consistency in product performance. Conducting high and low temperature, vibration and other environmental tests to ensure product reliability.
