waveform distortion (THD)
Record the power supply fluctuation without setting events
(15min to 1 day).

This can be omitted when urgent measurement is required.
Limit the number events to as few as possible at the beginning.
*Set the thresholds smaller and increase them gradually if too
many events are being recorded.
