Abstract
An automated measuring scale for making linear measurements includes a guide bar and an index marker that is moved automatically along the bar to predetermined positions commanded by the operator. A manually operated keyboard is provided to enter the position commands, and a digital display illustrates the commands as they are entered. The scale of movement is adjustable for an infinite number of variables, and the index marker can be repeatedly stepped along the guide bar by fixed increments when desired. In a manual mode of operation, the index marker is positioned to any location along the guide bar and the display automatically reveals the marker position in any selected scale.
