  • Variable color digital measuring instrument for sequentially exhibiting measured values
    Patent number: 6119073
    Abstract: A variable color digital measuring instrument sequentially exhibits measured values in a color in accordance with the relation of the present measured value to a past measured value. A memory, controlled by a timer, is provided for storing data representing the past measured value. A comparator compares the present measured value with the data stored in the memory and develops a comparison signal accordingly, which is then used to control the color of the presently exhibited measured value.
