How to Use a Theodolite?

1. Mark the point at which the theodolite will be set up with a surveyor’s nail or a stake. This point is the basis for measuring angles and distances.
2. Set up the tripod. Make sure the height of the tripod allows the instrument (the theodolite) to be eye-level. The centered hole of the mounting plate should be over the nail or stake.
3. Drive the tripod legs into the ground using the brackets on the sides of each leg.
4. Mount the theodolite by placing it atop the tripod, and screw it in place with the mounting knob.
5. Measure the height between the ground and the instrument. This will be used as a reference to other stations.

What Are the Disadvantages of Theodolite?

• Errors due to leveling.
• Inaccurate centering of theodolite instrument over station mark point.
• Error due slipping of lower plate of theodolite instrument.
• Taking reading wrong from vernier scale.
• Errors occur due to parallax.
• Errors due to not holding ranging rod vertically.

What Are the Different Types of Theodolite?

1. Repeating Theodolite: Repeating theodolites refer to those theodolites which measure angles on a graduated scale. The average of the angle measure is then derived. This takes place by dividing the total of these readings by the number of readings which were taken.
2. Direction Theodolites: Direction theodolites refer to those theodolites which determine angles through a circle. Here, a circle is set and the direction of the telescope is at several signals.
3. Vernier Transit Theodolite: Vernier transit theodolites are those which carry a telescope which flips over to allow back sighting and angle doubling. Most noteworthy, this result is quite a few errors in reading.
