Guide about Theodolite
Calibration Service which
used in Surveying
What is Theodolite?
Theodolite is generally needed for construction
work, which is used to measure horizontal and
vertical both angles. At Falcon Geosystems, We
assure total satisfaction by providing reliable
Theodolite Calibration Service in UAE which
traceable to national/International standard. We
are dealing with all different kind of instruments
and specialise in calibration and repair service of
survey instrument such as Theodolite, Total
Station, Leica Total Station, Nikon and Trimble
Total Station and GPS/GNSS Survey
Uses Of Theodolite In Surveying
 To measure something closely, we may need a theodolite. This tool is
really needed for construction work. To measure horizontal and
vertical angles Theodolite is a important tool.
 In its modern form, it incorporates a telescope aligned to make it both
ideal and vertical wet. Leveling is accomplished with the help of a soul
level; The crosshairs in the telescope allow precise alignment with the
visual object object. After the telescope is precisely positioned, the two
scales, vertical diagonally and horizontally, are read.
 In the field of civil engineering, workers need this to measure everyone
and all tasks can be done correctly. So, now you have questions as to
what this is and why do workers need to be used in construction work?
 Theodolite is used for many purposes, but is mainly used for
measuring angles, scaling points of construction works. For example,
to determine highway points, huge buildings' escalating edge lights are
used. Depending on the nature of the job and the precision required,
Theodolite makes the promise of a more curved face and using
different positions for swings or full-size surveys.
Uses Of Theodolite In Surveying
Theodolite helps us well in the engineering field. This
instrument plays a major role in measuring horizontal angles,
vertices, bearings, etc. To use theodolite, it is important to
know about theodolite parts, types of theodolite and how they
are used wisely in that area.Follow below important points,
where theodolite is widely used.
Measuring horizontal and vertical angles
Locating points on a line
Finding the difference in the level
Prolonging survey lines
Ranging curves
Setting out grades
Tachometric surveying
Steps To Calibrate Theodolite
For a potential building, it is necessary to mark the wall and the basic boundaries
through accurate angle calculations for the survey of the ground. In fact, many
surveys use theodolite electronic devices to view or view the area. These devices
provide accurate angle readings to determine the structural dimensions and
property boundaries. However, Theodolite will not be able to provide accurate
reading unless it is periodically calibrated, especially if the job site has excessive
machine vibration and wind. Follow the below steps for theodolite calibration
service .
 Place theodolite on a tripod that is approximately flat. Make sure the tripod legs
are firmly pressed to the ground for stability.
 Layer theodolite with its base-leveling screw, observing the bed's level bubbles.
Make sure the bubbles are centered in the visible area.
 Set a target about 300 feet away. The target should be like a plus sign or
 Look through the eyepiece of Theodolite. Align the inner crosshairs of
theodolite to the target's crosshairs. Notice the vertical wet angle displayed on the
front panel of Theodolite.
Steps To Calibrate Theodolite
 Staying in the same position. Turn theodolite around. Spin the eyepiece
until the user can see the target again without moving the position.
 Repeat step 4. The wet corners should match exactly. If vertical even
angles do not match, reset the electronic parameters of the theodolite with
the button again, effectively calibrating the theodolite to the new exact
 Repeat steps 4 to 6 for horizontal angle calibration.
 Test Theodolite with a set of well-known angle values, such as the
surveyor's baseline. Angles should match well-known values.
