Display unit for a measuring instrument
First Claim
1. A display unit for a measuring instrument with an image screen (4) to display arbitrary symbols composed of individual image dots (6), said image screen comprising pixel elements in the size of the image dots, said pixels elements being individually controllable by means of a control device (ALU, MEM, DR) and being arranged in the directions of a first dot-matrix axis and a second dot-matrix axis (V), wherein the control device (ALU), MEN, DR) individually controls said pixel elements such that a linearly shaped pointer element (25, 27;
-
36) is formed that gives the appearance of a line moving within the display and wherein the control device (ALU, MEM, DR) causes said pointer element to move slantedly across said image screen (4) based on a measuring value such that the pointer element maintains a constant slope angle (β
) in relation to the second dot-matrix axis (V).

Abstract
A display unit for a measuring instrument, particularly for a weighing balance (1), has at least one line-shaped pointer element (25, 27) presented as an image on a display screen composed of individually controllable image dots. The image dots are aligned in the customary dot-matrix arrangement along two grid axes. The display controller is programmed so that the line-shaped pointer element, as it sweeps through its display range, maintains a constant slope angle in relation to the grid axes.
