Abstract
Abstract Apparatus and method for improving the accuracy of weighing an object using a scale, when the object to be weighed may not be positioned completely on the scale, by performing a first weighing operation, slightly moving the scale on which the object is weighed, performing a second weighing operation, comparing the results, and providing an indication to the scale operator if the two results are not the same. The operator can then reposition the object to be weighed so that it is completely located on the scale, and perform a further weighing operation. The movement of the scale between weighings may be in a horizontal or vertical direction, or in a combination of the two.
