XL2000A Precision Electronic Balancer Balancing is clean and very profitable. Using the XL2000A - balancing to fine tolerances is so easy that almost any employee can do it with little training. To balance a crank, dial in two measurements of radius and three of distance. These measurements are easy to make yet very important; other units with just two inputs can't deliver as much precision. Spin the shaft and the digital displays show how much weight correction to make at exactly what point. With the drill press, you'll correct weight right on the balancer and check accuracy with no lost time.
