High precision dual line leveling research

The aim of this article is to investigate the accuracy of dual line leveling, and develop a methodology for its execution to enhance the precision of elevation determination by accounting for vertical refraction and controlling the non-horizontality of the leveling beam. Methodology. Considering that digital levels can measure distances to the rod and account for the non-horizontality of the beam and vertical refraction during measurements, we propose a method of dual line leveling.

Determination of the difference in the refraction coefficients caused by the variation in heights and the asymmetry of the leveling line profilesymmetry of the profile of the leveling line

The study of movement of the level Dini22 focusing lens

The experimental researches of the motion of the focusing lens of the digital level Dini 22 are done. The received results show that the precision of re-focusing of the specific level is within the precision of the measuring.
