How to adjust the level bubble of the level tube

The level is an instrument we often use for measurement. Adjusting the level bubble to make it level before measurement is the most basic skill. Next, let's learn the adjustment method of the level bubble together. How to adjust the level bubble of the adjustable level tube? I will give you a detailed introduction today.


  1. Rotate the two leveling bases simultaneously with the same amplitude, clockwise or counterclockwise, so that the horizontal bubble moves on the Central Line and finally moves to the center of the liquid cavity.

  If the leveling base is rotated clockwise or counterclockwise, the tilt of the balance will not change, so that the leveling bubble will not deviate from the Central Line. As long as there is no problem in the direction of rotation, it can definitely reach the center of the liquid cavity.

  Also clockwise or counterclockwise: Turn the base flat with both hands (one hand to the chest, the other to the chest, in the opposite direction, usually clockwise or counterclockwise).

  2. Turn left or right to level the base and adjust the leveling bubble to the Central Line of the liquid cavity.

  Rotate a left or right base separately to adjust the tilt of the balance, so that the horizontal bubble can be adjusted to the Central Line.

  The key is which one to flatten the base. Beginners can judge by manually tilting the electronic balance scale to make the leveling bubble reach the Central Line, and then look at the leveling base, which one is high or low. Adjust the height of one leveling base to make the leveling bubble move to the Central Line.

  To sum up, it is the introduction of how to adjust the level bubble of the level tube. It may not be easy for beginners to adjust the direction, and it is not easy to judge the direction. Here, we remind everyone that the range of both hands must be consistent. If not, the bead will offset the center line. If it's offset, you can start again from the first step. Anyway, you're good at it.
