Continuation
When the level no longer exceeds the trigger level we enter
the Con? state where we wait for the continuation time in
preparation to end the event. We continue processing event
data and transition back to the Valid state if the level exceeds
the trigger level during the continuation time.
Typical Icon Sequence
In a typical measurement, these icons will appear
