Electronic level EL50

The parallelism between the guide rails can be divided into two directions: horizontal and vertical. With the help of prism VP5-20 and electronic level EL50, the parallelism in both directions can be measured simultaneously, thus achieving the ability to adjust the parallelism in both horizontal and vertical directions simultaneously. At the same time, the electronic level can easily and accurately find the horizontal zero reference, so it can also obtain the levelness of the guide rail while measuring parallelism.
