Abstract
Abstract An all-digital and adjustable scale device comprises at least one load cell, a connection box and a controller housed within a controller main body. The connection box contains a plurality of A/D converters with input connected to corresponding load cell and output connected to a single-chip microcomputer. The controller comprises a control circuit having a microcomputer unit, a keyboard, a display and an interface. The microcomputer unit is connected to the single-chip microcomputer and the keyboard is arranged on the controller main body. The user can input command to the control circuit and controls the single-chip microcomputer through the control circuit for four-corner balance, adjustment, calibration and self-testing.
