Abstract

An improved counter for use with an incremental measuring device is disclosed which includes an up-down counter, a plurality of memory units, a computer, and means for designating any of the memory units. The computer is coupled to the counter and the memory units and is programmed to algebraically combine the value stored in the counter with the value stored in the designated memory unit to generate an output value for display. In the preferred embodiment, circuits are provided for setting the individual memory units to preselected values. The counter of this invention can be used to selectively display the measured position in any one of several measurement modes by designation of the appropriate memory unit.
