Abstract: Digital levels are a precise instruments used for precise leveling. Operation of digital levels is based on the digital processing of video indications of a coded staff. Changes in leveling methodology and sources of specific errors occur using digital levels for precise levelling. The marks on the leveling meters also are modified and consist from the coded strokes put on the meter’s surface in specific order. The accuracy of performance of all the measuring equipment mostly depends on accuracy of position of those strokes. This paper deals with an analysis of an accuracy calibration of leveling meters.
