Improvement of the scheme of technological verification of the digital level after its repair

To ensure the normal operation of the "digital level-barcode rail" system, it is necessary to annually perform its periodic verification to determine the image scale (average meter length), which is performed on a stationary interference comparator. In addition to the annual periodic verification, there is often a need for its exceptional conduct after accidental mechanical impact on the body of the digital level, which can lead to its repair. The main task in this case is to determine the working efficiency of the electronic channel of the digital level. Currently, these verifications are performed on a stationary interference comparator. The organizational disadvantage of this verification technique is a significant difficulty in its imple-mentation, since the number of interference comparators is extremely small, and they are located at a considerable distance from the sites of leveling work. This, in turn, leads to significant financial costs for its implementation. With this in mind, in order to ensure the procedure for conducting an exceptional verification, this article proposes a technique that allows it to be performed with the required accuracy at the site of leveling operations without using an interference comparator. This eliminates significant organizational and financial components in its implementation.
