LSM6DSL zero-g level offset accuracy

Hi everyone,

I'm using the lsm6dsl for acceleration measurement. But I'm getting big stationary offsets and I was wondering is that normal? 

Here are measurements from 5 different boards and all of them were carefully positioned to be exactly at the same place. 

 

xyz
-159-411110
-7-781037
86701100
10-981089
171221162

 

Is this normal operation? 

In datasheet Linear acceleration zero-g level offset accuracy is specified at ±40 mg (typ), but my measurements are as much as 6 times that.. Am I doing someting wrong? 

In the datasheet they say that sensors are all factory calibrated before they go out of factory, but I do not see any register or anything with calibration values. Only ones for user calibration.

 

I hope my message was clear, sorry for my English.

Thanks

Martin
