注意事项：在行任何测试之前，砝码都必须要清洁。清洁过程不能去除任何一块砝码材料。砝码在抓取和储存时都必须保持其清洁。清洁时不得改变砝码的表面特性（如：划伤砝码）。如果砝码上有灰尘，可以用干净的无水乙醇清洁砝码或局部。带有调节腔的砝码不得浸入溶液中，以免液体浸入腔体。

Note: before any test, the weights must be cleaned. The cleaning process does not remove any weight material. Weights must be kept clean while being grabbed and stored. Do not change the surface properties of the weights (e.g. scratch weights) during cleaning. If the weight is dusty, clean the weight or area with clean anhydrous ethanol. Weights with regulating Chambers should not be immersed in solution to prevent the liquid from entering the chamber.
