Abstract: A combination weighing device includes a conveying unit configured to convey articles, a controller configured to perform combination weighing of the articles, and an interface configured to receive an input of information from an operator. The controller has a first operation mode including a first control parameter that defines a conveying operation of the conveying unit and is automatically set in the device, and a second operation mode including a second control parameter that defines the conveying operation of the conveying unit and is set based on the information input from the interface, and when the interface receives an input of the information during an operation of the conveying unit in the first operation mode, the controller makes a transition from the first operation mode to the second operation mode, and controls the operation of the conveying unit using the second control parameter.
