What do you think of scales on traditional scales?

The weighing bar has two measuring ranges. One handle used is a large range near the weighing hook, and the other is a small range. The reading method is as follows:

1, small range: when looking at the scale from the side, the first cluster engraving point is the fixed disk star, that is, the zero scale line, the next scale is one or two, and the tenth scale is one catty, which are accumulated in turn;

2. Large range: right above the scale, the first cluster scale is the maximum weight value when looking at the small range, and then it is the same as above, and accumulated in turn.
