The main work is to measure the angle measurement instrument. By telescope, horizontal circle, vertical dial, spirit level, base and other components. When measuring the theodolite tripod with plumb bob or optical plummet instrument centering on the floor of the station, with a vial theodolite instrument set level, theodolite telescope aimed at measuring the production target with horizontal circle and vertical Direct dial measuring horizontal and vertical angles. Divided by accuracy and precision theodolite theodolite general; by reading equipment can be divided into optical theodolite theodolite and cursors; retest divided by shafting structure and direction theodolite theodolite. Single parallel plate micrometer reading device single parallel plate micrometer main components are: single parallel plate glass, fan-division scale and micrometer wheel. This instrument dial grid is 30 'industrial theodolites, fan partition on a 90-foot small grid, the grid is 30' / 90 = 20. "When the measured angle of rotation when targeting micrometer wheel, double After the index crossed the line clamp dial divided image reading integer degree readout dial according to the clamped sub scribe, lack of whole degrees from the measured differential zoned foot section reads industrial theodolite, theodolite, Jinke instrumentation by Instrument Co., Ltd.
