Abstract

PURPOSE: To ensure an accurate zero-point control by setting the integration period of the weighing value signal longer than the normal measuring time along with the control given so that the integration value may be zero in the integration period.
CONSTITUTION: In section I during which zeropoint control switch SW2 of control counter 4 is connected to side (a) of normal measuring time, 1st counter 8 performs 1000-pulse counting P1(c) at the beginning of the A/D conversion to prescribe weighing value signal integration period T1. And the integrator, featuring the output of (a), a starts the integration of value v at the end of T1, and counter 13 of display part 7 counts clock signal CL of AND gate 12 output (f) display 14. Then in section I where SW2 is connected to zero-point side (b), R-S.FF10 is set when 2000-pulse output P2 is given to CL(e), and the integration value becomes nearly double even with the weighing values signal featuring the same size as that of the normal measuring time. Thus the deflection amount near the zero point is magnified for display 14. As a result, an accurate zero-point control becomes possible in comparison with that in section I.
