ABSTRACT:
A device for quantified analog display, with planar structure, and measurement apparatus with multiple ranges and multiple operating modes using this display, which visualizes in analog form a value of a selected measured quantity among several. The display device comprises a flat substrate (2), a succession of identical electrodes (6) arranged side by side on one face of the substrate, and selectively excitable, and with at least one graduated scale (7) adjacent to the succession of identical electrodes (6) to determine the value of the measured quantity, in combination with at least one electrode of the succession of identical electrodes. The display device is characterized in that the graduated scale (7) is situated on the face of the substrate (2) bearing the succession of electrodes (6), and comprises at least first electrodes (9,11) forming a scale, and a number of sets of second electrodes (13-18), each set including a number of electrodes combining to compose two series of numbers, with the electrodes of the scales and those of the two number series common to the two series being connected electrically to a first output terminal (S23), with those specific to the first number series being connected electrically to a second output terminal (S24), and with those specific to the second number series being connected to a third output terminal (S25).
