Just like metal detection, there are two types of calibration associated with X-ray systems. Firstly in order to maintain designated Codes of Practice or HACCP protocols, X-ray systems should be calibrated once a year to normalize the detector and make sure the system is working correctly. Secondly an X-ray system will need to be calibrated for every new product so that the system can ‘learn the product’ and set up limits to achieve the best contaminant detection size possible. Once a product has been learnt once, it can then be recalled at the click of a button with no need to relearn unless there is a change in the product or if an error occurs.
