ABSTRACT:
When a measuring instrument normally displaying digital values by selective energization of a multi-segment display is used to furnish only qualitative information as to the relationship of the measured value to a reference value or values, the result is indicated only by the position on the display of a horizontal line. Since the change in position is limited by the position of the top and bottom segments constituting the digital display, the read-out of these conventional scales is difficult, particularly when carried out from different angles. To eliminate this problem, a reference mark or marks are supplied. The position of the weight dependent marks relative to the reference mark is clear, eliminating read-out errors. The reference mark may be a permanent mark on a transparent sheet mounted in front of the display. Alternatively, the reference marks can be created by activation of segments in places of the display not required for generating the weight dependent marks.
