The theodolite It is a type of telescope that can be used both in the horizontal and vertical planes to measure angles. The theodolites they are widely used by inspectors during construction projects. The instrument is operated by placing the telescope at one point, aiming the piece at the second measurement point, and then moving on to reading the measurement through the eyepiece.
Steps to follow:
1
Place the theodolite at the starting point for the measurement. The instrument location marks the first point at the angle you want to measure.
2
Adjust the theodolite height so that you can comfortably see through the eyepiece. Use the adjustment buttons on the instrument to adjust the height, pan, and focus.
3
Make sure the theodolite is perfectly level by adjusting the plumb bob. This piece is located under the telescope, at the bottom of the instrument.
4
Look through the eyepiece, moving it up or down to adjust the measurement angle. A red line will highlight the areas that are being measured. Horizontal and vertical measurements will appear on the viewing range side of the instrument.
