A system provides a more robust measurement of scanned items at a self-checkout station. The system comprises an item verifier for verifying placement of an item on a scale of a self-checkout station and a measurement adjuster operatively coupled to the item verifier for adjusting the item verifier operation in response to an error signal from the item verifier. In one embodiment, the measurement adjuster increases the number of samples for determining the weight of an item. By increasing the number of samples collected before determining item weight, the probability that temporary vibrations will not disturb weight measurement is increased. An exemplary method to implement the system includes verifying placement of an item on a scale and adjusting the weighing of the item in response to a failure to sense a weight that corresponds to the item placed on the scale. The adjustment may include increasing the number of samples collected or the time between samples.
