A microcomputerized electronic balance has a digital filter which filters the output of a weight transducer in the balance. The filter changes the amount of filtering in response to the resolution of a display in the balance, the desires of the user of the balance as reflected by the state of a manual data entry means manipulated by the user, and the stability of the balance. Use of such filter results in a stable display of weight related data and good response time for the display.

Electronic balance

An electronic balance having a strain gauge transducer. The analog output signal of the transducer is processed digitally so that the displayed weight is based on several successive digitized analog signal samples. Various operating parameters (e.g., conversion factors for several different units of weight) are stored in a non-volatile memory so that the scale can perform various weighing functions. The scale has a parts counter mode of operation requiring re-taring of the parts container whenever the scale is recalibrated for a different individual part weight.
