F2 Walkjump
As well as contact and flight times, the WalkJump test makes
it possible to acquire data for the length of the steps taken
during a run. To obtain significant data, it is essential to use a
certain number of OptoJump modules connected to each other
and then positioned along the sides of the test track.
After selecting WalkJump with F2, the following current
system settings are displayed:
Number of modules (press F1 to modify the value set):
6
specify the number of connected modules used for the test.
For the acquisition of step length data to be correct, this value
0 s
must correspond exactly to the number of modules installed.
C more
Start mode (press F2 to modify the value set): specify
'manual' if data acquisition is started by a signal on the
starting line (for example, by a photocell situated at the
F3 F4
beginning of the measurement base, or by pressing the start
key). Select 'autom' if you wish data acquisition to begin
automatically when the athlete being tested enters the test
base.
Timeout (press F3 to modify the value set): time elapsed in
seconds, the acquisition of which is automatically interrupted.
If the value '0' (zero) is set, acquisition finishes when an
impulse on the starting line is sent (or the start key is pressed).
When F4 (other) is pressed, other settings are displayed,
namely:
Minimum step length (press F1 to modify the value set):
specify the minimum step length – this value is used during
the acquisition of step length data to 'filter' possible false
steps resulting from double contacts with the ground (heel –
toe). Values below 20cm are not accepted. Racetime 2 always
C esc
approximates the value set to a multiple of 3.1115cm (which
is the interaxis between two successive data acquisition
F3 F4
points).
Entrance (press F2 to modify the value set): specify the
running direction. Int. side = the athlete runs the distance of
the base after entering from the side with the interface for
Racetime 2 or PC connection; cable side = the athlete runs the
distance of the base after entering from the side with the
connection cable between modules TX and RX.
Automatic acquisition (press F3 to modify the value set):
select 'yes' if you want the system to automatically set itself
to acquisition mode after each passage of an athlete, so as to
make it possible to register two or more passages completely
automatically.
