LIS331DLH的自检输出更改

嗨，


我们开发了一款使用LIS331DLH加速度计的产品，并对目前的结果感到满意。

我的问题涉及自测输出变化，可能高于规范中规定的变化。数据表表示120到550或140和750 l***，具体取决于轴。但是，我看到输出变化超过1000 l***。

我们仍然可以使用电路板，这是否意味着组件在组装过程中已经损坏？与重力相比，测量结果似乎一致。
我们是否应该提高代码中的阈值级别，如果是，那么建议的级别是多少？

谢谢

Hi,


We have developed a product which uses the LIS331DLH accelerometer and are happy with the results so far.

My issue concerns the self test output change which can be higher than stated in specifications. The datasheets indicates between 120 and 550 or 140 and 750 l*** depending on the axis. However, I have seen output changes above 1000 l***.

Can we still use the boards, does it mean that the component has been damaged during the assembly process? The measurements seem consistent otherwise when comparing with the gravity.
Should we raise the level of the thresholds in our code, if so what level would be recommended?

Thanks
Marc
