Zero-g level offset of LIS2DH12 at FS bit set to '11', and Normal resolution mode.

LIS2DH12, Zero-g level offset is 40mg at FS bit set to '00'.

When using the FS bit set to '11' and Normal resolution mode, what value is it?

40mg * 12 = 480mg ?

or

40mg * 48 = 1920mg?

    ST doesn't specify this value.

    But I would expect that if the zero-g level at FS=2g is typically 40mg, for FS=16g it could be 8-times higher.

    Dear Miroslav BATEK,

    Thank you for your reply.

    But, I don't understand if zero-g level offset is affected by resolution mode(High resolution or Normal or Low-power).

    Do not I have to worry about the resolution mode?

    I don't think the resolution will have significant impact on the zero-g level.
