3 Overview

Electronic theodolite (hereinafter referred to as the theodolite) is a goniometer with automatic compensation, electronic goniometer with digital display instrument.

Such equipment is mainly used for national third-class, fourth-wire measurement and triangulation control surveying, mining, railways, highways, Engineering survey work bridges, farmland, water conservancy and other aspects, can also be used to install large-scale machinery and equipment.

Its accuracy class with one measuring instrument nominal standard deviation mbeta horizontally divided as shown in Table 1.

Table 1 Accuracy classification

Instrument grade I II III IV Standard deviation ( ") mbeta<=1.0 1.0 \u003cmbeta<=2.0 2.0\u003cmbeta<=6.0 6.0\u003cmbeta<=10.0 4 legal management requirements 4.1 units of measurement Theodolite legal units of measurement should be used.

4.2 legal metrology marking and measuring instruments logo Theodolite shall be marked with the manufacturer (or factory standard), model and serial number of domestic theodolite measuring instruments must be made Manufacturing license number (of new products can leave the corresponding position) and mark. Theodolite with laser should be in a prominent position Set marked with warning signs.
