6.2 Set position function
In the
Set Position
mode the chair is moved to a pre-
defined position; a default “Zero Position”.
After a test the chair will move to this position.
If the examiner wants to define a second “Zero Position” where the chair faces a
screen or similar,
this position is defined in relation to the default Zero Position.
Overview:
Comments:
a.
After a test the chair returns to the default zero position which we define as zero degrees. As
an example we now want the patient to face an object which is 180° to the right (a half cycle)
of the zero position. The value „180‟ is entered in the window, and the „Start‟ button is
activated. The chair must perform a rightward half cycle rotation.
b.
For leftward movements towards
the second zero position simply add a „minus‟ sign before
the value, like in “
-
180°”
c.
Velocity: low values such as 20°/s produce slow movements, whereas high values such as
100 °/s produce fast movements.
