ABSTRACT:
A weight measuring apparatus comprises a load cell for generating an analog signal corresponding to load applied, and A/D converter for converting an output signal from the load cell into a digital signal, a data processing unit which periodically reads a digital output signal out from the A/D converter to successively write the digital output signal into a first memory area of the memory and produces data corresponding to the weight of load applied to the load cell on the basis of plurality of digital data stored in the first memory area of the memory to write the data into a second memory area of the memory, and a display unit for displaying the data from the data processing unit.
The data processing unit compares a plurality of digital data stored in the first memory area. As a result of the comparison, when a given number of or more digital data having the same values are included in the digital data stored in the first memory area, the digital data is produced as output data. On the other hand, when the digital data having the same values fail to reach the given number, the digital data stored in the second memory area and the latest or newest one of the digital data read out from the A/D converter are compared. When the difference between the two compared digital data exceeds a given value, the latest digital data is produced as output data. When, on the other hand, the difference is less than the given value, the data stored in the second memory area is read out and outputted.
