VERIFICATION OF A LASER LEVELING DEVICE FOR PROVIDING REFERENCE PLANES

摘要

The present subject matter relates to verification of horizontalness or verticalness of laser beams produced by a laser leveling device (102). In one embodiment, a method for verification of the leaser leveling device (102) include directing a first laser beam onto tubes (104) which are in fluid connection with each other. The method further includes measuring a distance between a level of liquid in the tubes (104) and marked position of the first laser spot formed due to the first laser beam for each of the tubes (104). The method further includes determining a maximum deviation and comparing it with a first threshold value for determining whether the laser leveling device is fit for measuring horizontalness.
