Accelerometer data range and value roll over at acceleration > 10G

Is there any documentation on the maximum range of accelerometer data? It seems that once ~10G occurs in an axis the value for that axis rolls over.

I am using a fenix 7 and get accelerometer data in a callback at 50Hz (using the new higher rate capability in sdk 6.3.x)

10G is not that high and can easily be reached by just throwing ones arm up when jumping.

Is anyone experiencing this?

  • I did some asking around, and what you're seeing is by design. There are hardware and configuration limits in place, in addition to performance considerations we have to account for, that keep the accel tuned to somewhere in the +/-8 G range (don't quote me on that—just an estimate).
