Drugs can not be put directly, and they must be restored after weighing. Brief description: 1 The main components that make up the balance of the tray are the (adjusting zero point) screws, the rider code, the scale, the pointer, and the tray (the left and right two points). 2 Before weighing, you should first check whether the balance is in balance.
