Tips: How to measure verticality with a laser level?

When measuring the verticality of large parts, use a level to roughly adjust the reference surface to a horizontal position. Use a level to measure step by step on the reference surface and the measured surface, and use the graphic method to determine the reference orientation, and then calculate the perpendicularity error of the measured surface relative to the reference.

When measuring the verticality of small parts, first place the laser level on the reference surface, read the value of one end of the bubble, and then use the side of the laser level to stick to the surface to be measured. The first reading value of the bubble deviation from the reference surface is The verticality error of the measured surface.

When using a laser level meter, ensure that the working surface of the laser level meter and the surface of the workpiece are clean to prevent dirt from affecting the accuracy of the measurement. When measuring the horizontal plane, in the same measuring position, the level should be adjusted to the opposite direction before second measuring. When moving the level, the working surface of the level is not allowed to rub against the surface of the workpiece, and it should be lifted and placed.
