Witty User Manual - EN - v1.5 P. 59 / 171
To carry out this type of exercise, set the test as follows
Delay: Insert the delay in tenths of a second, after which Witty·SEM turns on
the direction change arrow. The parameter is set, calculating approx.
the time the athlete takes from the last impulse before the traffic light
to the direction change point.
Number of impulses Number of impulses after which Witty·SEM displays the arrow. In
example 1 it is set to 1 (start photocell before the traffic light); in
example 2 below, it is set to 2 (start + lap1).
Direction This indicates the directions Witty·SEM displays; the possible selections
are left/right, left/right/forwards, left/right/forwards/backwards
Number of Repetitions Indicates how many times the sequence “break photocell + turn on
semaphore” occurs. It is useful to create a number of Gate/Sem
“groups”, see example 3.
The sequence takes place as follows:
Witty·SEM off– start impulse – half a second wait (5 tenths) – appearance of the right or left arrow – stop
impulse – Witty·SEM indicates its index (A,B,C). Pressing <F1> New, the sequence restarts.
