Abstract

PURPOSE:To perform stable display by displaying the weight in the form wherein drifts are always compensated. CONSTITUTION:The current value of the digital data of the weight is stored in a register 3 and the previous data is stored in a register 4. The difference between the contents of both registers is monitored by a difference detector 5. When said difference becomes larger than the preset value, a counter 6 performs counting and clearing operations. A stable flipflop 7 memorizes stable and unstable states. In a register 8, is provided a circuit containing the content of zero. In a register 9, is provided a circuit containing computed difference between the registers 3 and 4. The contents in the registers 8 and 9 are inputted to an adder-subtractor 11 via a gate 10. When the stable flipflop 7 is in a stable state, the gate 10 is opened, and the zero-point data is added or substracted by the difference between the registers 3 and 4. A weight computing part 12 computes the weight value and displays it on a display 13.
