ABSTRACT:
A digital measuring method an apparatus for displaying quasi-analog measured values performs the steps of displaying a measurement scale and interconnected triggerable indicator segments on a display having a given indicator center distance, representing a measured value to be indicated by the position of the indicator segments, controlling the resolution of the quasi-analog measured value display in dependence of the number of indicator segments triggerable within a measurement period to be represented, setting the resolution substantially lower than a resolution with which an A/D converter connected to the display operates, and subjecting a control command for triggering an actual indicator segment to a hysteresis, which assures that a switchover from a previous indicator segment to an actual indicator segmet does not take place until the actual measured value has increased or decreased by substantially more than one-half the given indicator center distance.
