In the initial state, it is set to 2 channels (Ch0 and Ch1 are used).
In the initial state, sampling is performed 1000 times at a cycle of 1
millisecond (1000uSec), and the result is displayed on the chart.
Since the initial state is
sampling of 1000 times with 1 millisecond cycle, signal change per second
is displayed on the chart.
