Abstract
Apparatus for visually indicating to an operator of a vernier, for example, that he is approaching a desired set point. The apparatus additionally indicates when the exact set point has been reached. This is accomplished with the use of a display, preferably a liquid crystal display, which has an exact set-point indicator provided on either side with two arrows pointing toward the set-point indicator. When the control parameter is far to one side of the set point, the large arrow on one side of the set point will be energized; and as the set point is approached, the large arrow will be extinguished with the small arrow remaining energized until the exact set point is reached, whereupon all arrows are extinguished and the set-point indicator energized.
