How to verify accelerometer data is correct or not?

[ATat.1]

I have read the accelerometer data using(H3LIS100DL) sensor then I got some negative value x=-3, y=-2, z=-1. I used these register OUT_X(29h), OUT_Y(2Bh), OUT_Z(2Dh). My question is how to verify these accelerometer X, Y, Z data is correct or not?

Hi, usually ST sensor shows 1g along z axis and close to 0g along the other axis.

Probably for the H3LIS100DL the zero g offset is higher (+-1.5g I see from the datasheet), since the full scale is high.

LSB and mg are of same order of magnitude and can be negative.

You can try hitting the device and see if the output on some axis change significantly.
