Abstract
The invention provides a display device for a rotary balancing machine. The balancing machine generates a digital out of balance weight signal of value W at an angular position .theta. with respect to a datum angle to indicate value and position of a weight required for balancing purposes. In the display device the weight signal is fed to a pre-programmable read only memory programmed to provide a digital output equivalent to an angle of arc cos ( W/2W.sub.1) where W.sub.1 is a predetermined weight to be used for balancing purposes. Angles .theta..sub.1 and .theta..sub.2 such that .DELTA..theta.=.theta.-.theta..sub.1 =.theta..sub.2 -.theta. are normally displayed but for calibration purposes can be suppressed to enable signals W and .theta. to be displayed. Weights of the predetermined value placed at angles .theta..sub.1 and .theta..sub.2 should completely balance the wheel.
