High accuracy FOIF Dsz1 Automatic Level is used in 2nd or 3rd order leveling and in geodetic control, construction of roads and industrial applications,and in monitoring structural deformation etc. It is up-graded from DSZ2. Standard deviation of 1KM double run leveling of DSZ2 is 1.0mm. While the accuracy of DSZ1 is 0.7mm/km. The compensator improves performance and obtaining higher efficiency.
