Abstract

The features of metrological calibration tests of surveying instruments, particularly digital levels are described. The procedures for investigating “digital level – barcode rod” system are offered that allow determining for a barcode-rod image scale. Such procedure can be used both in the laboratory of industrial company having digital levels and in the field conditions. The laboratory bench is also offered to determine basic specifications of levels with visual reading, “digital level – barcode rod” system, and total stations as well. The necessity for carrying out instrumentation calibration in the field is caused due to mechanical shocks of a digital level when transporting that can lead to the disadjustment of a level’s electronic system. As a result of this a barcode-rod image scale can be changed.
