Abstract
A system and method of validating checkweigher performance (weighing accuracy). The invention involves removing an object to be weighed from a conveyor prior to the object reaching a checkweigher to be validated, weighing the object on a static scale, reintroducing the object to the conveyor upstream of the checkweigher, weighing the object with the checkweigher, and comparing the two weight readings of the object to determine if the checkweigher is accurately weighing objects. Validation objects may be automatically removed from the conveyor by a transfer mechanism.
