Abstract
A method for rotationally positioning a rotor for balancing procedures uses an instrument within a housing that is temporarily mounted to the axial face of a rotor for determining rotational locations with respect to a reference mark located on the rotor. The instrument has a needle indicator which is responsive to gravity, and is mounted such that it can rotate independently of the position of the housing. Tick marks representing degrees are arranged in a circle around the edge of the needle indicator. Two sets of numerical scales are provided, each in a different color, one increasing in a clockwise direction, and the other increasing in a counter clockwise direction. Two arc shaped arrows are provided, one each in the two colors used for the two sets of numerical scales. The color of the arc shaped arrow that points in the direction of incremental rotor rotation indicates that the set of numerical scales printed in the same color should be used for reading the degree of rotation. The method overcomes operator confusion as to the direction in which rotational angles should be measured by associating rotor operational rotation and measured rotational angles with the color coded arrows and color coded numbers on the instrument.
