Advantage and disadvantages of Autolevel

Advantage of AutoLevel

• Autolevel is very easy to use its use very simple for civil engineers.
• Not correction for staff reading is required in Autolevel as the actual reading is seen from the eyepiece.
• The bubble can be adjusted from any side and any angle with any 3 screws available for Autolevel.
•  Autolevel has an internal compensator mechanism which automatically adjusts the line of sight.
• The measurement accuracy of the auto level is  very higher.
• Autolevel results are very faithful.
• Ease of use of Autolevel saves money and time.
• The price of the Autolevel is low and economical.

Disadvantages of Autolevel

  Vertical angles cannot be measured in Autolevel

how to use Autolevel 

AutoLevel is a level with a compensator.

Auto Level Setup

1. Setup your tripod as level as possible, step on tripod legs to drive into the fields.

2. Attach Autolevel to the tripod (fix).

3. Adjust level so bubble is centered point in wall.

4. Adjust recital until crosshairs are clear.

5. Adjust the objective lens until object you are sighting on is clear and see The measurement accuracy of the auto level is higher than the dumpy level. 

difference betwen auto level and dumpy level instrument use in leveling

Auto level and dumpy level are two different instruments used in leveling.

	Auto Level	Dumpy Level
1	In the auto level, no adjustment for staff reading is required as the actual reading is seen from the eyepiece	In the dumpy level survey, staff reading need to be adjusted as inverted level staff reading is seen in the eyepiece.
2	In the auto level, the bubble can be adjusted from any side and any angle with any 3 screws available in auto level	In the dumpy level, to level the bubble, one has to keep bubble parallel to two leveling screws and then right angle to the third screw.
3	The auto level has an internal compenstor mechanism which automatically adjusts the line of sight.	Line of sight is manual adjusted in dumpy level.
4	The measurement accuracy is better than dumpy level of auto level.	dumpy level are difficult to measure accurately.
