COMBINATION BALANCE, AND METHOD OF WEIGHING OBJECT TO BE WEIGHED BY USING THE SAME

PROBLEM TO BE SOLVED: To provide a combination balance that performs additional dropping-in of an object to be weighed without replacing objects by discharging an object to be weighed when discharge combination is not able to be performed, and can raise a probability of discharge combination in combining calculation after the above process, and to provide a method of weighing an object to be weighed by using the combination balance. SOLUTION: When there is not a discharge combination as a result of performing of first combination calculation in which a discharge combination based on a target combination weight is calculated by a first combination calculation means 31a, a temporary target combination weight calculation means 31b sets a weight obtained by subtracting a central weight value of an object to be weighed held on a discharge hopper at present from the target combination weight as a temporary target combination weight. A second combination calculation means 31c performs a second combination calculation for calculating an additional combination based on the temporary target combination weight. After that, an additional dropping-in weight calculation means 31d calculates a predetermined range including an additional dropping-in weight corresponding to the additional dropping-in combination so as to display it on an operation setting display device 8.
