Accurate weighing and measurement of fine materials is provided by a linear compensation apparatus and a weighing system. The linear compensation apparatus has a weight loading mechanism () with a bearing plate (), a drive apparatus (), and a measuring weight (). The drive apparatus is mounted onto the bearing plate, the measuring weight is connected to the drive apparatus, and, by hoisting or lowering the measuring weight with the drive apparatus, loads from the bearing plate are adjusted. The linear compensation apparatus and the weighing system greatly reduce device costs and labor costs in a batching process, save time and effort, have no risk of cross-contamination, and achieve automated production operation.

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.
