Installation and adjustment; â‘  All components need to be wiped clean before installation. The back of the hanging tray is marked with "1" and "2", and should be installed according to "1 left and 2 right". After installation, the handwheel should be turned to make the crossbeam rise and fall several times. Adjust the support screw when the crossbeam falls, so that the crossbeam does not twist when it rises and falls. When falling, the middle knife edge should leave the middle knife support, and the hanging tray should just fall on the base. â‘¡ Adjust the level of the balance base: Adjust the leveling screw to make the bubbles on the base in the middle position of the circle marking line, Indicates that the balance has been adjusted to the horizontal position. â‘¢ Adjusting the balance of the crossbeam: Use tweezers to move the cursor to the left zero mark, turn the handwheel to slowly raise the crossbeam, based on the central line of the scale, so that the pointer swings equally on both sides. If not, lower the balance screws on both ends of the crossbeam adjustment crossbeam, and then raise the crossbeam... Repeat this process, Until the crossbeam is balanced. Another point should be made clear: for the entire crossbeam system of the balance (including two hanging plates), the center of gravity is located directly below the knife edge. The sensitivity of the balance is related to the distance from the center of gravity to the knife edge. Adjusting the position of the sensing weight can change the center of gravity position of the entire crossbeam system. The higher the center of gravity position, the closer the distance from the knife edge, the higher the sensitivity of the balance, and the smaller the sensitivity. For a balance, When it leaves the factory, its sensing weight position is adjusted, and the sensitivity of the balance is determined. Generally, do not touch its sensing weight during use
