ABSTRACT:
An analog voltage representing the weight of an article being weighed is provided by a strain-gage type load cell. The analog voltage is converted into digital weight value data by means of an analog/digital converter. If the weight value data which are provided after the lapse of a predetermined time period following the turning on of a power supply, are within a predetermined range, the weight value data are stored in a memory as an offset value. The data stored in the memory are used for subtraction from further weight value data are displayed in digital manner by a display. If the weight value data provided after the lapse of a predetermined time period is off the predetermined range, a renewal setting of the offset value in the memory is prevented.
