ABSTRACT:
The multi-segment indicator can be selectively switched to operate as a range display. For this purpose, the vertical segments are deactivated. Each digit in the multi-segment indicator has a top, bottom and middle horizontal segment. If the measured value is, respectively, less than equal to or greater than a desired value, all bottom, middle, and top segments, respectively are activated. Alternatively, all middle segments are activated if the measured value is within a desired range, the top and bottom segments being activated if the measured value is, respectively, greater than the upper limit of the range or less than the lower limit of the range. The sign of the measured, desired, and limiting values is considered before activation of the corresponding horizontal segments.
