PROBLEM TO BE SOLVED: To provide a combination balance for easily determining a stability waiting time for satisfying the predetermined weighing accuracy. SOLUTION: In the combination balance 1 which is constituted to obtain a weight signal by supplying a to-be-weighed object from a supplying hopper 5 to a weighing hopper 6, a dynamic weight measurement value is obtained from the weight signal at each time among a plurality of different dynamic weight measurement value obtaining times after a time when the to-be-weighed object is supplied from the supplying hopper 5 to the weighing hopper 6, and a static weight measurement value is obtained from the weight signal at a static weight measurement value obtaining time after a plurality of different dynamic weight measurement value obtaining times, so that the dynamic weight measurement value obtaining time during an actual running operation is determined as the dynamic weight measurement value obtaining time when the magnitude of an error is a predetermined acceptable value or less by an evaluation of the magnitude of the error of the dynamic weight measurement value to the static weight measurement value.
