Placement method theodolite 1) tripod tune into equal length and height for the operator theodolite wire, the instrument on a tripod, the instrument on a tripod base surface and parallel to the top surface. 2) the instrument placed on dance station theodolite industry, currently estimated roughly to the after-foot step on a steady and adjust the optical plummet eyepiece (see the cross hairs) and objective (see the station), with The hands put a frame around the feet, side to side, Grossly coincides with the intersection of the crosshairs allows the station, put stability and real step foot frame. 3) telescopic tripod legs to level the circular level 4) the vial given two parallel flat spiral, leveling vial. 5) pan alidade 90 degrees, with a third screw leveling vial. 6) Check the optical plummet, if a small amount of deviation, can open a connection to spiral pan base, making precise alignment theodolite, tighten the screw connection, and then check the level bubble in the middle.

Note eliminate parallax. Fine pointing targets. ③ reading: Adjust the lighting mirror theodolite offer, so moderate reading window brightness, rotation reading microscope eyepiece makes clear scribe line, and then reading.
