ALSO Calibration means that the equipment was adjusted back to nominal. Whether this is correct or not depends on the calibration laboratory's service definitions or what was agreed between the supplier and customer. It means that adjustment to return an item to specification compliance may, or may not, be performed. Unless the Certificate contains a statement affirming that the item met the published specification it is merely a report of the measurements made. In this case it is left to the equipment user to review the data against requirements.
Some equipment is more expensive to have calibrated than to purchase a new one each year.
Just scrap the old item which was probably worn anyway. It could be that a calibration certificate is not provided with the new purchase. Some users are not concerned, perhaps relying upon the manufacturer's reputation to deliver new products that are specification-compliant which may be a justifiable risk. Less justifiable is the suggested practice to dispose of the old item without first getting it calibrated. Only measuring equipment with the possibility of adjustment needs periodic calibration.
