LIS2DH12TR   have  some questions for help below:

1. The captured accelerometer data found that there was a fixed frequency of jitter, and I wanted the manufacturer to determine whether it was a problem with the hardware itself
2. I would like to ask the manufacturer whether the accelerometer needs to be calibrated at the factory or powered on
