NOTE: The calibrator must have no more than one screw installed on its rotor
disk when used with the 8500C; however, the calibrator was designed to have at
least two screws 180 degrees apart. To simulate a second screw, enter the
actual rpm (half the "CAM RATE") as the balance frequency and "2" as the times
factor in the 8500C balance setup display. For example, if the CAM RATE is
900, enter "450" as the balance frequency and "2" as the times factor.
