The glass beads of the electronic balance in my laboratory are not balanced, how to do it

We know that newly purchased electronic analytical balances and electronic balances should be warmed up for more than half an hour before use before weighing operations. Before the electronic balance is energized, we need to level the electronic analytical balance. By adjusting the two knobs at the back of the electronic analytical balance base for effective adjustment, when the level bead is adjusted to the center of the circle in the middle of the position, it can be energized to preheat.
