4 Overview

Optical theodolite is a precision optical instrument for measuring horizontal and vertical angles, it is widely used in engineering surveys, Geodetic and measurement work. Optical theodolite (hereinafter referred to as theodolites) by a nominal standard deviation rounds horizontally divided into the following levels. DJ07, DJ1, DJ2, DJ6, DJ30.
