Abstract
PURPOSE: To faciliate and accelerate measuring operation and heighten the accuracy of measurement, by displaying the quantity of variation in an indicated zero point as apparently zero if the mean value of the variation is within an allowable range when the variation is stabilized within an allowable width.
CONSTITUTION: When no piece is no a balance 2 and the minute output signal Dr of an A/D converter 4 is applied to a stabilization detecting comparator 20, the signal is stored into a sampled value memory register 23 by the comparator at every sampling. The comparator 20 compares the signal Dr with stored values within a time set by an averaged stabilization time setting unit 21. If the stored values exceed an allowable fluctuation, width, all the stored values are erased. Subsequently, sampling and comparison are repeated. When it is found out that none of stored values exceeds the allowable fluctuation width, these stored values are applied to a calculation and data control unit 9 which averages the values. A minute range detection comparator 7 works so that the averaged value is indicated on a digital display unit 5 if the average value is out of an allowable minute range but apparent zero is indicated on the display unit if the average value is within the range.
