Sure, if your produce scale is off, you might miss out on a few cents, but if the weight of, say, a 15-wheeler is off, that could pose some major safety risks. 38 33 Now you are ready to perform parts counting for the specific samples. Properly established scale tolerances, calibration proce- dures, and scale functional tests are very important issues for QA programs and production costs. ���K���r���趃Xg����3jm��L��Ѷ�9Y���������.���sv� tx�@ �$�ҕ�1x�2�|V��7x���{�e�p>���`Эf�(�%-|�f���T��s���T CK�`�C���+�[�V���5�|Ѿ"��\ �[����Gŵ6�&�զ��z����OO$�W�i�nָ���pY�m���s�r_N~*�����'����z��O����Y�qe�����S�!~�q�,f���-YW���g3��ɭ7��֎�&}�+�:��o��ϯ�y�]������Ɯ�;暜�j����?x����ʮ�����շM D��-p����u��_n� &N4&Z���lE/�F;�̋F���ME��Eҵv'��L�qQ�7��H Put certain pieces of objects on to the scale pan.
