How do you read a transit level?
How to Read a Transit Level
- Locate the eyepiece.
- Up the scope of the level is the leveling vial.
- The knob at the end of the scope is the focusing knob.
- The horizontal graduated circle is the circular guide marked with degrees, used for reading horizontal angles.
How do you level ground in transit?
Set up the transit level. The device is affixed to a solid three-legged or four-legged base. Press the feet of the base firmly into the ground. Adjust the legs until the spirit level, a small vial of liquid containing a bubble, shows it as level, with the bubble centered between the lines.
How do you use a transit to level ground for a swimming pool?
Setting up a Transit Push the legs firmly into the dirt. Set the transit carefully on the mounting plate. Turn the locking screw underneath until snug. Level the mounting plate to the center of the vial bubble, by adjusting the sliding legs slightly or the leveling screws, until the bubble is perfectly centered.
How do you measure ground level?
To Measure Ground Slope:
- Hammer a stake into the ground next to your home’s foundation.
- Tie one end of the string around the stake at ground level.
- Measure out 10′ from the foundation, and hammer a second stake into the ground.
- Pull the string taut, and tie the end around the second stake.
How is ground elevation measured?
Take the total length of your string and divide it by the length of your level. Since this number equals the total difference in elevation from each post, multiply this number by the calculated distance between the string and level.
How does a surveyor determine elevation?
The elevation is calculated by subtracting the foresight rod reading from the height of instrument. A foresight is the elevation reading of a point of unknown elevation. The rod could be moved to other points as shown in Figure 13, and similar calculations would determine the elevations of these points.
What is transit leveling?
Transit levels use a telescope to find a level line across a long distance. Survey transit leveling is a common option for landscaping, construction and surveying. There are many different types of transit levels, but most use a tripod base, calibrated rod and eyepiece. What Is the Difference Between a Builder’s Level and a Transit?
How do I level the transit level on my Telescope?
Place the level directly on the tripod head. Thread or bolt the transit level onto the tripod base. Remove the protective lens covers and place them in the carrying case. Place the sunshade on the telescope. Your transit level is mounted. Make sure that the tripod is stable and securely planted before starting the leveling process.
What are the different parts of a transit level?
The basic setup of a transit level consists of the actual transit level, a tripod base, a tape measure, and a calibrated rod. The transit level itself consists of many parts: Here’s more information further explaining parts of a transit level and what exactly they do including, telescopes, leveling vials, base plates, alidades, and verniers:
What is a graduated leveling vial on a telescope?
The stadia lines get bisected by the vertical crosshair which allows the user to find out the distance of the object being sighted. The graduated leveling vial is also known as a spirit level. The spirit level is used to level the telescope while it is being placed on the base and works much like a traditional hand level.
