|TOP DEAD CENTER METHOD||
This is used when measuring the parallelism or levelness of rolls. With the target facing the laser, the roll is rotated slightly back and forth until the highest point is determined, which is the top dead center of the roll. This should be used when tight tolerances are needed or when it is difficult to determine if the target is near top dead center, usually when measuring vertical rolls.
