According to the operation mode, into which two categories can weighing instruments be classified?

According to the operation mode, weighing instruments can be classified into automatic weighing instruments and non-automatic weighing instruments.

Automatic weighing instruments can automatically weigh and display or print the measured mass value, such as dynamic rail scales, quantitative packaging scales, etc.

Non-automatic weighing instruments require manual operation to complete the weighing process, such as platform scales and counter scales.

按照操作方式，可将衡器分为哪两类？

按操作方式，衡器可分为自动衡器和非自动衡器两类。 

自动衡器能自动称量并显示或打印被测质量值，例如动态轨道衡、定量包装秤等。 

非自动衡器则需要依靠人工操作来完成称量过程，如台秤、桌秤等。
