Figure 41 Plotter view of KX132-1211 with FFT functionality (ADP channel)

If there is a need to change the threshold values, then the proper threshold values can be seen from the plotter view and then written to the sensor

using the register editor see (

1.4.3.4Stream modify mode

) for details.
