Abstract:
A dual variable color measuring system comprising:first means for measuring a first signal and including a first data output for developing first data indicative of a measured value of said first signal;second means for measuring a second signal and including a second data output for developing second data indicative of a measured value of said second signal;a single display device including a plurality of light emitting diode display elements arranged in a side by side relation within said display device, each for providing a character indication in a selective color, and each including a color control input for illuminating said character indication in a first color in response to a first color control signal and in a second color in response to a second color control signal;means, responsive to said first data output, for providing a character indication of said first data on certain ones of said light emitting diode display elements;means, responsive to said second data output, for providing a character indication of said second data on the remaining ones of said light emitting diode display elements;first color control means, associated with said first means for measuring, for applying said first color control signal to those of said color control inputs, corresponding to said light emitting diode display elements on which said first data are exhibited, for illuminating said character indication of said first data in a first color; andsecond color control means, associated with said second means for measuring, for applying said second color control signal to the remaining ones of said color control inputs, corresponding to said light emitting diode display elements on which said second data are exhibited, for illuminating said character indication of said second data in a second color;whereby said character indication of said first data and said character indication of said second data are exhibited on said display device in a side by side relation and distinguished by different colors.
