When using the balance, it should be placed on the flat workbench. 2. Move the cursor to the “0” point on the left end of the ruler: the pointer should be aligned with the center line of the header to obtain balance. Otherwise, the balance nut on the lever should be turned to adjust the balance. 3. After the balance is adjusted, place the object to be weighed in the left disk, and add the weight from the big to the small in the right disk. Try to put the item and weight in the center of the weighing plate, when increasing or decreasing to the minimum. When the weight is still unbalanced, the movable code can be balanced. The mass of the object is equal to the sum of the mass of the weight and the mass of the travel code. 4. After the weighing is completed, the travel code
