Abstract
PURPOSE: To prevent an integrated A/D converter from being broken, when an abnormal voltage is established, by providing a voltage clipping circuit at the input side of the A/D converter.
CONSTITUTION: The output of a load cell 2 for generating voltage signals in accordance with the load is amplified at 3 and fed through a voltage clipping circuit 6 to an integrated A/D converter 7 so that the load may be metered in a digital quantity. As a result, even if the output of the amplifier 3 is raised to an abnormal level when a power source is made, the excessive voltage is clipped to prevent the integrated converter 7 from being broken.
