Abstract: A position measuring instrument of the type having a scale and a scanning unit is provided with a plurality of reference marks on the scale. An identification mark is associated with each reference mark, and each identification mark is uniquely coded. The scanning unit operates to read the identification marks and to generate identification signals which are applied to a comparator or to a computer. The comparator or computer compares the identification signal corresponding to each reference mark with a set of designation signals. Only if a correspondence is found between the identification signal and one of the designation signals is the reference mark allowed to go into operation. Thus, by merely changing the designation signals electronically, any desired subset of a total number of reference marks can be enabled. The selected reference marks can readily be changed electronically without physical manipulation of the measuring instrument.
