    Yeah I’ve worked IT in a food production environment and am familiar with setting up the products. When we went from catch weight (price per kg) to fixed weight products like ops we got loads of calls about packs being rejected and initially didn’t understand why until reading more into how e weighing rules work. I can’t remember the specifics as it was sometime ago but only a certain percentage can be below the target weight and above T1 and a smaller percentage can be between T1 and T2 which are the fall back weights.

    Fortunately these rules are preprogrammed into checker weighers and weight price labellers so they setup is easy it’s just getting the weights right going into those machines with minimum giveaway (if the batch weighs more than the the pack count x target weight that is called giveaway).
