PROBLEM TO BE SOLVED: To determine abnormalities in each digital load cell readily and accurately, in a gravimetric device using a plurality of digital load cells. SOLUTION: By providing an unbalanced load output determination means, an output deviation calculation means, and an abnormality determination means and on the assumption that each of a plurality of digital load cells is connected and installed appropriately, the presence or the absence of unbalanced load output from the respective digital load cells is determined; output deviation is calculated when there is no unbalanced load output; and it is determined as being abnormal, when the value of the calculated output deviation is larger than a prescribed reference value and a warning issued.
