What do you think of the traditional saying?

The traditional scale is a "pole scale"

On the hook (tray) of the steelyard, there will be two hanging ropes for weighing different weights, which are equivalent to two upper range gears of the multimeter.

The hanging rope near the front is a "large range", and the scale is on the upper side of the balance beam. Because of its heavy weight, the scale is slightly thicker, usually taking "0.5 kg" as the unit; The hanging rope near the back is a "small range", and the scale is on the side of the weighing beam close to the human body. Because of its small weight and fine scale, it is usually "two" as the unit. Now the scales are also measured in kilograms, not kilograms and two. If there are flowers, big flowers represent one kilogram.
