The electronic analytical balance will produce measurement errors due to uneven placement during the weighing process. The higher the weighing accuracy, the greater the error (such as analytical balance and micro-electronic balance). For this reason, most electronic balances provide the function of adjusting the level.

How to Adjust the Level Bubble of Electronic Analytical Balance

The electronic analytical balance will produce measurement errors due to uneven placement during the weighing process. The higher the weighing accuracy, the greater the error (such as analytical balance and micro-electronic balance). For this reason, most electronic balances provide the function of adjusting the level. 1. Rotate the left or right leveling base to adjust the level bubble to the central line of the liquid cavity first. Rotating a left or right leveling base alone is actually adjusting the tilt of the balance, and you can definitely adjust the level bubble to the central line. The key is to adjust which leveling base. Beginners can judge this way, first manually tilt the balance to make the level bubble reach the central line, then look at the leveling base, which one is higher or lower, and adjust the height of one of the leveling bases to make the level bubble move to the central line. Note: After reaching the central line, the next step 2 can be adopted. Rotate the two leveling bases at the same time. The amplitude must be the same. Both must be clockwise or counterclockwise. Let the leveling bubble move in the central line and finally move to the central leveling base of the liquid cavity and rotate clockwise or counterclockwise at the same time. The balance inclination will not change, so that the leveling bubble will not leave the central line. As long as there is no problem in the rotation direction, it can definitely reach the liquid cavity center. Rotate clockwise or counterclockwise at the same time: both hands rotate the leveling base at the same time (one hand to the chest, one hand to the chest, in the opposite direction, usually rotating the base clockwise or counterclockwise at the same time) direction problem: it is not easy for beginners to judge the direction. You can manually raise the base or another support to move the blister 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 there is no agreement, the bead will shift from the central line. If it is offset, it is OK to start again from the first step. After proficiency, the level bubble of a precision electronic balance can be leveled in 1-2 minutes.
