PURPOSE:To suppress the fluctuation in displayed value due to temporary disturbance and the like and to change the displayed value at a quick response speed when a load is changed, by increasing and decreasing the number of data in response to the state of the data appropriately, and computing an average value. CONSTITUTION:Converted digital data from a load detecting part 11 is received by an RAM15 of a control part 12. The RAM15 has an area, wherein the maximum of m+1 data are stored. When the the newest data (do) arrives, the oldest data (dm) is discarded every time. At every time data sampling is performed, an average value Wo of the newest data, whose number is specified (i) pieces in the RAM15, is computed. When the deviation between the average value Wo and the newly accepted data (do), i.e., (do- Wo), does not satisfy an expression I (where R is the precision degree of the electronic balance), the data is judged to be changing. When the expression I is satisfied, it is judged that the data is proceding to a stable state. With the precision degree of R of the electronic balance as a judging reference, the stability of the data is judged. The number of data for computing the average value is appropriately increased and decreased, and the average value based on the most effective number of the data can be displayed. |
