This paper presents the analysis of preciseness and safety of different instruments for researching the vertical displacements of the objects in the space. In Slovenia researching the objects by the test of pressure is obligatory for all structures, which are longer than 15 meters (JUS U.M1.046). Among all the methods we choose geodetic as well as non-geodetic ones. There are many methods for researching the displacements, so we took limits to the instruments available to us. On the Faculty of Civil Engineering, University of Maribor, Slovenia, used the level, total station, and inductive transducer and laser level. The measures of displacements were made on the reinforced concrete plate, type PVP5. For the plate we calculated the foreseen displacements by the analytic as well as by the numeric method. For analytic calculation we used the national regulations (Euro code 2) and for numeric part we used the programme Ocean. For each instrument we calculated the standard deviation and the optimal accuracy, we checked the significance of results by the analysis of variances with one variable factor. In this paper we described all the instruments for following the displacements and the working principles of instruments by which the research was made and the measurement errors. The analysis of precise was made on the base of comparation between the results of foreseen displacements and the gained results of measurements. The results of this research are gathered in a conclusion and give us the answer to the goals.
