Dear,
Could you let me know the way to measure the non-linearity?
In the datasheet, it shows +-0.5% at 2g FS. So, I think you may test from 0.5 ~2g every 100mg or 50mg or etc.
In the case of Kionix, they do it as below.
Hi,
Thanks for your inquiry.
Tilting accelerometer each axis at different angles can measure the nonlinearity in the range from -1g to +1g. In order to determine the nonlinearity at full scale range of +/-2g, +/-4g, +/-8g or +/-16g, you can follow the Kioinix app note by using a shaker.
Thanks.
