Event Marking
Event Marking allows for the Brake Trigger channel to display a change in state – an „event‟ in a
logged file which can be useful for measuring distances etc.
The Brake Trigger channel defaults to a value of 0, until the an event is marked (see pages 22 or
31) at which point the value will become 1. The Brake Trigger channel should be set up in the
software so that this can be easily observed, by assigning its axis in a manner such as this:
Note how in the example above, the axis has been set from –0.5 to 1.2 – this allows for the change
in values from 0 to 1 to be very obvious on the graph. If you do not want the constant value of 0 to
be displayed, set the lower axis level to 0 – the event mark will then be displayed as a „spike‟ in the
graph.
The example above demonstrates an event created by the user holding the OK button on the
DriftBox for five seconds: the event will continue to be recorded for as long as the button is
pressed.
