  • Patent number: 11879770
    Abstract: A weighing method has an automatic micro-calibration function. In the method, an automatic adjustment is performed by a self-calibration weighing module. When the result of the adjustment does not meet a requirement, an automatic calibration is performed by the self-calibration weighing module, followed by weighing fine formulation materials. In the weighing method, the self-calibration module is used to perform the automatic calibration function to weigh the fine formulation materials. This provides a high degree of automation, and greatly reduced cost in equipment and labor for a formulating process, saving on time and labor, and with no risk of cross-contamination.
