Results and Live Move
l V is the vertical orientation of the machines viewed from the side.
l H is the horizontal orientation of the machines viewed from the top.
l The foot results which are used in correcting misalignment are position values with
respect to the reference machine.
l The bold colored foot tolerance arrows show the direction and magnitude in which to
move the machine. The color code also shows the attained alignment tolerance.
