ELECTRONIC WEIGHING SYSTEM WITH DIGITAL READOUT

摘要

An improved electronic weighing system with a digital readout. A transducer establishes an analog signal corresponding to an unknown weight. The analog signal is amplified, digitized with an analog-to-digital converter and applied to the digital readout. Circuitry is provided for automatically zeroing the analog portion of the system while the transducer output is momentarily interrupted and for filling gaps in the analog signal resulting from the interruption of the transducer output. The digital portion of the system also includes tare weight provisions for modifying the indicated weight, and circuitry for changing the range and the resolution or increment of the weighing system.
