By setting each counter input in the "Channel Setting" column and executing it, sampling of the count value of Ch 0 (the first input terminal) is performed.
In the initial state, sampling is performed 1000 times at a period of 1 millisecond (1000 μSec), and the result is displayed on the chart.
Since the initial state is
sampling of 1000 times at 1 millisecond cycle, the change in the count
value for 1 second is displayed on the chart.
