4 Overview

Non-self-indicating scale is based on the principle of the lever balance designed entirely by personnel to operate the machine to obtain the equilibrium position Scales that increase or decrease by increasing the mound and (or) Amusement mound move on the scale to balance the weight of the measured object, by metering bars Swing rod to determine the state of equilibrium, so as to obtain the weighing indication. Non-self-indicating scales include a variety of mechanical lever Scales, such as mobile text scales,, fixed floor scale, to the scale and so on.
