Hi, We are experiencing "glitches" on the ACcelerometer values once in a while. we are using 52Hz rate. expected values are 1000mg +-100mg on the Z Axis. Once in a while we see several samples going down significantly.

Hi,We have been using LSM6DSOX in our Pool Alarm Unit.The Device is floating horizontaly in the pool and valid Z axis Acceleration is around 1000mg.We are currently facing a problem that is caused by seldom "glitches" on the Accelerometer values.Devi...
