Impulse duration defines how long the
output signal remains in the activated
state. Impulse duration can be set to a
value within a range of 0 to 10.000 ms
by pressing the + or the – key.
If the value is set to “0 ms” the function
is deactivated.
After the selected impulse duration has
elapsed, the output signal is returned
to the deactivated state..
Function can be combined with
ON Delay.
