Abstract
A deviation meter, responding to a deviation signal, is mounted on a turntable which rotates in response to a set point adjustment. Rotation of the turntable maintains the null position of the deviation meter pointer at a scale position corresponding to a set point value, so that a direct readout of the actual measurement value is provided.
