A surveyor's theodolite is used to measure horizontal and vertical angles. These measurements are used to plot purlieus lines, building foundations and utility routing. A theodolite measures distance manually by chains of standardized length or metallic measuring tapes along the length of the desired angle. Country-surveying students use a theodolite every bit a way to acquire the principles of bending measurement. Surveying on the job requires the use of more-advanced surveying instruments.
Drive a surveyor'south nail into the ground at the point where you desire to set up the theodolite. Angles will exist measured from this bespeak, as volition distances.
Prepare the tripod legs, taking care to gear up the height where the instrument sight will be at a comfortable eye level. Be sure to bank check that the hole in the centre of the mounting plate is located over the nail. Printing each leg into the ground by stepping on the subclass at the bottom of each leg.
Fine-tune the position of the legs and so that the mounting plate on the top of the tripod is every bit eye-level every bit possible.
Remove the theodolite from the instance. Most theodolites have a sturdy handle on top. This is the best place to elevator the instrument. Gently place the instrument on the mounting plate and screw in the mounting knob beneath the instrument.
Adjust the theodolite to level by adjusting the tripod legs, using the bull's-eye level. Fine-tune the adjustment with the leveling knobs on the instrument.
Adjust the minor sight, called the vertical plummet, at the bottom of the theodolite. This sight allows yous to make sure the instrument is centered straight over the boom. Fine-tune the vertical plummet by adjusting the knobs on the bottom of the theodolite.
Look through the main scope and aim the crosshairs at the signal to be measured. Twist the locking knobs to hold the theodolite in position on the verbal point. View the horizontal and vertical angles in the viewing telescopic on the side of the instrument.
