When executed, the voltage (or current) value input to Ch0 (the first input terminal) is sampled.
In the initial state, sampling is performed 1000 times at a cycle of 1 millisecond (1000 uSec), 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.
If you want to set the input
method, you can add setting to [Channel setting].
