Electronic analytical balances will produce measurement errors due to uneven placement during the weighing process. The higher the weighing accuracy, the greater the error (such as analytical balances and micro electronic balances). For this reason, most electronic balances provide adjustment levels. Function. 1. Rotate left or right to level the base, and adjust the level bubble to the center line of the liquid cavity first. Rotating a left or right leveling base alone is actually adjusting the inclination of the balance, and the level bubble can definitely be adjusted to the center line. The key is to adjust which leveling base. Beginners can judge like this: first manually tilt the balance to make the leveling bubble reach the center line, and then look at the leveling base, which one is higher or lower, adjust the height of one of the leveling bases to move the leveling bubble to the center String. Note: After reaching the central line, the next step can be used. 2. Rotate the two leveling bases at the same time, and the amplitude must be the same, both clockwise or counterclockwise, so that the level bubble moves on the central line, and finally moves to the center of the liquid cavity for leveling If the base rotates clockwise or counterclockwise at the same time, the inclination of the balance remains unchanged, so that the vial will not deviate from the center line. As long as there is no problem with the direction of rotation, it can definitely reach the center of the liquid chamber. Rotate clockwise or counterclockwise at the same time: Rotate and level the base at the same time with both hands (one hand to the chest, one hand to the outside of the chest, in the opposite direction, generally rotating the base clockwise or counterclockwise at the same time) Orientation problem: not big for beginners Easy to judge the direction. You can manually raise the base or another support to move the blisters to the center, and then observe the position of the leveling base to see if it needs to be raised or lowered. Note that in the second step, the amplitude of both hands must be the same. If they are inconsistent, the drop will shift from the center line. If it shifts, just start again from the first step. After proficiency, the level bubble of a precision electronic balance can be leveled in 1-2 minutes.
