Now drive the upper arm using the keys
'+' and '-' until the lower arm (more 
precisely: the plane determined by the two
centering pins) is located parallel to 
the base plate.

Confirm the position using 'Enter'.

As before, the ROB3 again drives to 
this position 'dynamically' and you have
the possibility of correction.

After pressing 'Ctrl-Enter' the position-
ing is terminated. Now measure the 
distance of the centering pins: elbow to
base plate (with the lower arm oriented
horizontally) as exactly as possible and 
enter the value using 'Enter'.
