The results of experimental studies of the error in the counting of the rail by theodolite OLSH are presented. It is established that in the conditions of a closed building of an industrial enterprise the error of counting on a rail is almost two times greater than calculated by known formulas. Recommendations are given for the calculation of errors in the calculation of the accuracy of geodetic measurements performed in enclosed premises of industrial enterprises.
