Abstract
The experience of using SDL30 electronic level during tests of the Trinity Bridge in St. Petersburg conducted in May 2003 is described. The deflections of spans were determined by the results of high-precision geometric leveling. The characteristics of the level used and some test results are given. The use of electronic levels significantly reduced the time of leveling and perform a large amount of work by one team of surveyors. It is proposed to use the electronic level, which allows to speed up significantly the measurement process and get rid of the routine work of processing the results.
