Adjust the balance of balance once the balance moves, if you want to continue to use, you still need to adjust the balance placed level, and adjust the beam balance (also called no-load balance), otherwise, can not be used directly. If used, the measurement is not accurate.
It must be noted that when adjusting the beam balance of the balance of the balance of the object (also called the balance of the load), it is absolutely not allowed to adjust the balance nut
