ABSTRACT:
A digital measuring device for a quasi-analog measurement value indication includes a display for the measurement value indication, a pre-determined overall measuring range disposed on the display, a measurement value scale forming a spread measuring range section of the overall measuring range with variable spreading, the measuring value scale being addressable in planar segments with alpha numeric characters, an indicating device for indicating a value on the measuring value scale, and an automatic control placing measurement values within the displayed measuring range section with numerically displayed scale values fitting the measuring range section, with the overall measuring range remaining constant and the measuring range section having a selected spreading factor.
