Generally, there are two scales, that is, there are two handles that can be lifted. The one closer to the hook or tray is for large quantities, and the one farther away is for small quantities. They are also called "first scale" and "second scale".

They respectively correspond to the two numerical values ????superscripted on the scale. According to the numerical value, the value of each scale can be calculated. This is a bit like the reading method of a multimeter.
