Abstract:
An adjustable electronic scale comprising:at least one load cell for output of an analog loading signal responsive to a pressure force applied thereto; at least one A/D converter connected to the at least one load cell and converting the analog loading signal of the load cell into a digital loading signal provided at an output thereof; a single-chip microcomputer connected to the output of the A/D converter and receiving the digital loading signal therefrom, the single-chip microcomputer manipulating the digital loading signal to output an output signal; and a control circuit having an input connected to the single-chip microcomputer and receiving the output signal therefrom for further processing and output of signals representing a value of force loading corresponding to the pressure force, the control circuit having an input for a user to input commands for controlling the single-chip microcomputer through the control circuit for initiation of four-corner balancing, adjustment, calibration and self-testing.
