Abstract

A display apparatus (10) having a display (12) including indicia representative of a measured parameter, an indicator (13) shiftable relative to the display, and a control assembly (14) for controlling the positioning of the indicator relative to the display. The control assembly includes a microprocessor (16) for receiving navigational signals and for converting the navigational signals to control signals and a stepper motor (18) responsive to the microprocessor for driving the indicator in response to the control signals. The control assembly also includes an indicator position sensor (20) for determining the actual positon of the display indicator and for generating position signals representative of this actual position. The microprocessor uses these position signals for calibrating the stepper motor.
