ter. At the bottom of the screen as below, present count value of the selected channel
is displayed by the Counter value text box. You can start or stop the counter to count
by clicking the Star/Stop button next to the Counter value text box. You also can reset
the counter (the value in the register will be initialized to zero) by clicking the Clear
button.

ter when the module power off.
