The main work is to measure the angle measurement instrument. By telescope, horizontal circle, vertical dial, level control, base and other components. Theodolite measurement configuration, the theodolite tripod, with a plumb bob or optical plummet instrument centering the station on the ground, with a vial theodolite instrument set flat, with a telescope aimed at measuring the goal, with horizontal and vertical dial Direct dial measuring horizontal and vertical angles. Divided by the accuracy and precision theodolite ordinary theodolite; by reading device can be divided into optical theodolite and vernier theodolite; divided by shafting structure and direction theodolite theodolite retest. Single parallel plate micrometer readout single parallel plate micrometer main components are: single parallel plate glass, fan-division scale and micrometer wheel. This instrument dial grid is 30 ', the sector division on a 90-foot small grid, the grid is 30' / 90 = 20. "When the goniometer theodolite, when targeting micrometer wheel rotation, with double indicators After clamping the dial points crossed the line image reading integer degree according clamped sub dial dash readout theodolite offer insufficient degree the whole section from the measured differential readout feet zoned single parallel plate micrometer reading device single parallel plate micrometer main components are: single parallel plate glass partition sector and micrometer scale wheels, this instrument dial grid is 30 ', there are 90 small cells on the sector division ruler, Georgia. value of 30 '/ 90 = 20. " When measuring angle rotation when targeting micrometer wheel, rear grip with dual dial indicator points crossed the line image reading. Read the whole degree according clamped sub dial dash, inadequate entire degree from the measured differential draw foot section reads. Theodolite quotes, theodolite, Jinke instrumentation provided by Qingdao Branch of the Instrument Co., Ltd. Qingdao Branch of the Instrument Co., Ltd.
