Help¶

The maximum time interval that can elapse between the start of the acceleration on the selected channel exceeding the specified threshold and the end when the channel acceleration goes back below the specified threshold. The resolution depends upon the sample rate (ODR) and the high-pass filter configuration (HP_FILTER_CUTOFF[pls_hpf_en]). For ODR=800 Hz and pls_hpf_en=0, the resolution is 0.625 ms/LSB.
