LSM9DS1TR gravity expected output

Hi, I am using a LSM9DS1TR, with accelerometer scale set to +-16G.

With the device motionless on a table, I read a decimal value of 1360 for the Z axis, and if I flip the board over I read -1360 (give or take a few counts). So, this is obviously measuring gravity.

I would however have expected gravity to be 1G, so I would have expected an output of 1/(16/32768) = 2048, not 1360.


Can anyone explain why I do not see what I expect to see? I've obviously missed something!
