IIS3DWB: how to detect over range

Palmering

Hi,

I'm using the IIS3DWB accelerometer to get triaxial waveform.

I just want to know what is the best approach to detect over range.
I tried to compare sample by sample in each channel with the maximum possible positive value (>32766) and the maximum negative value (<-32767) but I didn't get overflow detection when the peak acceleration > range.
When I set the limits to +/-16384 (half) my detection routine works (with an instantaneous acceleration value > range/2).

What is the measured acceleration value when the acceleration is over the full-scale range?
Does the accelerometer limit the the value to the maximum?

Best regards
