    Patent number: 3944737
    Abstract: A circuit for improving the accuracy of a video measuring device which removes errors caused by variations in the horizontal deflection voltage by continuously monitoring the horizontal deflection voltage and comparing it with a preset reference voltage and adjusting the horizontal deflection voltage if any variation from the reference occurs. This assures that measurements made with the video system remain accurate at all times and measurements can be made with great accuracy.
