Claim 0:
1. A weighing method with an automatic micro-calibration function for material tank scales, said weighing method comprising the steps of:
installing and connecting a material tank to a self-calibration weighing module and a control system;
sending an instruction, by the control system, for performing an automatic adjustment to the self-calibration weighing module by, at least, electronically commanding the self-calibration weighing module to load the material tank with a predetermined calibration weight, displaying loaded weight data, and subsequently:
determining in the control system whether the loaded weight data meets a predetermined requirement;
only if the loaded weight data does not meet the predetermined requirement, instructing, by the control system, the self-calibration weighing module to perform an automatic calibration;

weighing fine formulation materials using weighing control on the fine formulation materials by a feeding system of the material tank; and
switching, by the control system, back to calibrated data for the material tank, and subsequently weighing large-weight mixed solvent materials.
