PROBLEM TO BE SOLVED: To prevent a weighing defect from occurring without lowering weighing capacity.SOLUTION: A combination balance comprises: a setting operation part 11 for setting stable waiting time with a point of time at which a weighed object is supplied from a supply hopper 12 to a weigh hopper 13 as an origin; and stability determination means for determining whether or not a load signal is stable on the basis of the load signal during a prescribed period around a point of time at which the stable waiting time passes. As the stable waiting time, a fixed time is determined in advance which is the first prediction time from the origin until the load signal becomes stable or more when the supply of the weighed object from the supply hopper 12 to the weigh hopper 13 is in a normal state, and which is less than the second prediction time from the origin until the load signal becomes stable when the supply of the weighed object is not in a normal state.SELECTED DRAWING: Figure 1 |
