Frame level is mainly used to check the flatness of various machine tools and other equipment. Verify the correctness of the horizontal and vertical positions of the installation, and can also check for small tilt angles. Its measurement accuracy includes: 0.2/300, 0.5/200, etc. A frame level is a square universal angle measuring instrument that utilizes the principles of liquid flow and liquid level to directly display small tilt angles relative to horizontal and vertical positions using a level bubble.

usage method:

The two V-shaped measuring surfaces of the frame level serve as the benchmark for measurement accuracy and should not come into contact or rub against rough surfaces during measurement. When placing, care must be taken to avoid damaging the level and causing unnecessary measurement errors due to scratches on the measuring surface.

When measuring the vertical plane of a workpiece with a frame level, one should not grip the part opposite to the secondary side and instead apply force to push towards the vertical plane of the workpiece. This will cause deformation due to the force on the level, affecting the accuracy of the measurement. The correct measurement method is to hold the inner side of the secondary measuring surface with your hand, so that the level is smoothly and vertically attached to the vertical plane of the workpiece (adjust the bubble to the middle position), and then read the number of grids in which the bubble moves from the longitudinal level.

When using a level, it is necessary to ensure the cleanliness of the working surface of the level and the surface of the workpiece to prevent dirt from affecting the accuracy of the measurement. measure

When on a horizontal plane, at the same measurement position, the level should be adjusted in the opposite direction before measuring. When moving the level, water is not allowed

If there is friction between the working surface of the leveling instrument and the surface of the workpiece, it should be lifted and placed.
