PURPOSE:To make it possible to perform highly accurate measurement all the time, by automatically performing span calibration for every specified temperature, and limiting the measured value within the range of specified errors all the time. CONSTITUTION:An input signal to an A-D converter 13 is made to be a signal from a temperature sensor 16, and the converted digital data (t) is received. When the difference between said data (t) and temperature data 10 at the time of previous span calibration is not larger than a preset temperature T, the input signal to the converter 13 is made to be a signal from a load detecting part 11, and the converted digital data W is received. The data W is converted by using a counted number K stored in a memory 14b at present. General operating processes such as subtraction of tare weight and zero-point correction are performed. The measured display value is determined and displayed on a display device 15. Thus the highly accurate measurement can be always performed. |
