The optical level of SETL DSZ3 represents the traditional geodetic device allowing to define a difference of heights with use of a leveling lath by a geometrical method.
The error of the device does not exceed 1,5 mm by 1 km of the double leveling course therefore SETL DSZ3 carry to group of exact levels. High precision allows to use an optical level for performance of measurements to which increased requirements are imposed. Among them: control of high-rise installation of designs, quality check of work of linear personnel, measurement of collapsible deformations of constructions, etc. Also you can use this model as a standard when carrying out checkings of other measuring instruments.
Unlike the majority of high-precision tools, SETL DSZ3 has the wide range of working temperatures, from –40º-С to +50º-С thanks to what the possibility of performance of measurements in different climatic conditions is provided.
Measurements at big distances are possible thanks to 30-fold increase in a telescope of a level. With its help you can carry out vising on remote pickets with a big shoulder, without changing the device location. At the same time the minimum distance of vising of an optical level of SETL DSZ3 makes only 50 cm. It allows to use effectively this model and in short distances, for example, in buildings on floor flights.
The automatic compensator independently establishes the line of vising of a telescope in the horizon. It increases efficiency of measurements and provides constancy of provision of the measuring plane at pushes and fluctuations of the basis. The pendular system of the compensator of a level of SETL DSZ3 is equipped with the air damper providing fast calm of a suspension.
Like other optical levels, SETL DSZ3 it is traditionally equipped with a cotton range finder for expeditious measurement of distance to a leveling lath. The horizontal limb of the device provides fast trace of the directions. It significantly simplifies process of creation of high-rise justification and leveling shooting. The dioptric viewfinder placed on the top side of the case allows to carry out more precisely preliminary aiming of a level at a lath at the expense of what the general time of performance of measurements is reduced.
