A device for setting various operational parameters of combination weighing machine, such as target weight, speed of operation, name of product, allowable range of weight, hopper gate opening time and feed conveyor operation time. In this device, it is only necessary to manually register some independent operational parameters such as target weight and speed of operation from a keyboard and, then, the remaining dependent operational parameters such as hopper gate opening time and conveyor operation time can be registered automatically in accordance with the previously registered independent operational parameters.

Operational condition setting device for combination weighing machine

An automatic span adjusting device incorporated in a weigher for correcting deviation of the weight signal provided by the weigher from the true weight of product being weighed by the weigher, the device including a memory storing weight values of a plurality of reference weights for span correction and means for automatically reading one of the stored weight values from the memory to provide it for calculating a span correction coefficient.
