The TG328A photoelectric analytical balance belongs to the equal arm lever balance,where the fulcrum is located in the middle of the line connecting the force point and the key point.In theory,it requires the left and right arms to be completely equal,but in practical use,it is impossible to achieve complete equality.Therefore,balance calibrators,repair personnel,and users need to have the ability to detect the degree of unevenness of the balance and corresponding adjustment capabilities.
