In order to ensure the precision of Laboratory Electronic Balance, we must adjust the position of the Balance and do the calibration work. Laboratory Electronic Balance horizontal bubble is mainly used to observe whether the position of the Balance is in a horizontal state. Which side of the horizontal bubble bias, indicating that the side of the high, should be counter-clockwise rotation level foot adjustment to make it lower? The rotation rule of the horizontal adjustment foot is clockwise → rise; anticlockwise → lower. To adjust the electronic balance, you need to rotate both hands and adjust the level foot, one hand to the chest, one hand to the chest, in the opposite direction, according to the following tips:

1. When the horizontal bubble is above the horizontal circle, it indicates that the Laboratory Electronic Balance is high above. We need to rotate the upper two corners of the Laboratory Electronic Balance to move the bubble down.

2. When the horizontal bubble is on the right side of the horizontal circle, it means that the right side of Laboratory Electronic Balance is higher. We need to rotate the two corners on the right side of Laboratory Electronic Balance to move the bubble to the left.

3. When the horizontal bubble is below the horizontal circle, it means that the Laboratory Electronic Balance is high below. We need to rotate the lower two corners of the Laboratory Electronic Balance to move the bubble up.

4. When the horizontal bubble is on the left side of the horizontal circle, it means that the left side of Laboratory Electronic Balance is higher. We need to rotate the left side of Laboratory Electronic Balance's two corners to make the bubble move to the right.
