Study of various parts of Auto Level
Introduction
Surveying or
land surveying is the technique, profession, art, and science of determining
the terrestrial or three-dimensional positions of points and the distances and
angles between them. A land surveying professional is called a land surveyor.
These points are usually on the surface of the Earth, and they are often used
to establish maps and boundaries for ownership, locations, such as building
corners or the surface location of subsurface features, or other purposes
required by government or civil law, such as property sales. You can look at
the lecture notes, browse through slides, and also see an animation that can
run several examples.
This
experiment is useful to study all the equipments used for surveying as well as
for auto level. It contains the audio, visual as well as the cross sectional
view and description of each part of equipment.
An auto level, an automatic level is a professional leveling
tool that is often used by land surveyors, builders, contractors, and
engineers. And it’s best known for its ability to provide consistent level
accuracy more quickly than many other leveling instruments. It’s usually placed
on a tripod, where it’s calibrated to a level position with leveling screws.
The person operating the device then looks through the telescope that’s
attached to the instrument, while a second person holds a graduated staff or tape
measure at the position that needs to be measured.
An auto level can be used in many different
applications, which can include but may not be limited to:
- Structural framework.
- Establishing proper drainage systems.
- Determining the correct elevation of floors.
- Establishing the proper height for doors and windows.
- Developing suspended ceilings.
The
steps to calibrate an auto level:
Step-1) Place the instrument on a tripod,
while pointing it at the collimator.
Step-2) Turn the leveling screws to make
sure they can move freely.
Step-3) Look at the bubble vial to make
sure the bubble isn’t larger than the circle.
Step-4) Move the bubble to the center of
the circle by using two of the three leveling screws.
Step-5) Make sure the bubble stays center
at 90, 180, 270, and 360 degrees.
Step-6) Rotate the eyepiece focusing knob
to both extremes, while focusing on the instrument’s cross hair (or reticle).
Step-7) Rotate the focus knob so it’s
first on close up and then on infinity to make sure the movement is smooth and
even.
Step-8) With the focus set to infinity,
check the cross hair of the instrument to make sure it matches with the reticle
on the collimator.
Step-9) Use the adjusting screw next to
the eyepiece to move the cross hair up and down until it matches with the
collimator.
Steps to perform experiment -
Step-1) There are two buttons in the
experiment i.e. Back Button & Next Button
Step-2) Back Button:It is used to go to
previous page.
Step-3) Next Button:It is used to go to
next page.
Step-4) Use these two Buttons to proceed.
Step-5) Use Finish Button to restart the
experiment.
