Note 2 : If the time axis on the oscilloscope screen deviates or to
move to a clearer position on the screen, adjust finely using
Delay. However, do not change the vertical axis and
horizontal axis ranges.
Note 3 : When reading the waveform on the oscilloscope screen,
read the center of the waveform noise.
Note 4 : If the oscilloscope signal waveform is difficult to read,
adjust the luminance.
