Method Of Using Theodolite
Dec 29, 2018

1) The tripod is adjusted to the same length and is suitable for the operator's height. The instrument is fixed on the tripod so that the base surface of the instrument is parallel to the top surface of the tripod.
2) Place the instrument dance on the station, and estimate the center of the machine. Step on the foot and adjust the optical centering eyepiece (see the crosshair) and the objective lens (see the clearing site). Lift a frame foot forward and backward, swing left and right, and see the centering device to make the intersection of the crosshairs coincide with the test site, stabilize and step on the foot.
3) Telescopic tripod leg length flattening level
4) Level the leveling tube parallel to the two parallel spirals and level the leveling tube.
5) Flatten the sighting section 90 degrees and level the leveling tube with a third spiral.
6) Check the optical alignment. If there is a small amount of deviation, open the connection spiral translation base to make it accurately centered, tighten the connection spiral, and check the level bubble centered.
