I question came to me today regarding the daily verification of high capacity weighing scales used in phamaceutical production. This is in reference to scales with capacities of 500kg and higher. I have not seen daily verifications of high capacity weighing scales but am very familiar with the practice of performing daily / pre-use verification of analytical balances in compliance with USP <41>. Does anybody have any experience with production plants performing daily verifications of high capacity weighing scales? If so, are the checks done to capacity or some fraction of the scale capacity?
