Hold-off State
Turns on or off the trigger hold-off function.
Hold-off Time
Sets the hold-off time between trigger signals. You can use the numeric keys, the
knob, or arrow keys to modify this parameter; you can also use the touch screen to
modify the parameter.
When the trigger conditions are met, the trigger occurs. Then, the delay begins, and
the hold-off time begins. During the hold-off time, new trigger signals will be ignored.
For a free-running trigger, the hold-off value is the minimum time between two
trigger signals.
