It is named so because of the shorter telescope it uses and also because in the original dumpy level the eye piece was an inverting lens such that it gave a shorter view for the same power of lens compared to wye level.
Dumpy level provides a horizontal line (parallel to earth's curvature); you can read the scale by holding it normal to the ground level. Take separate readings for separate points then compare them
a procedure-level variable
actually it is the c which is known as medium level language because it can perform operations bit by bit as a low level language and is suitable for making any application software as a high level language
No. Java is a high level language also known as object oriented programming
High-level to binary is known as compilation or interpretation, depending on whether the entire program is converted at once (compilation) or only one statement at a time is converted (interpretation). There is no conversion from binary to high level -- it's one-way only.
it is a spirit level
The auto level makes it easier to do the work. Using the dumpy level requires you to put in all of the work.
It as 3 following steps to adjust the dumpy level 1.SETTING 2.LEVELLING.3FOCUSING
One advantage of the dumpy level is that it is extremely mobile. A disadvantage is the difficult in using and making accurate measurements.
Dumpy
To perform a permanent adjustment to a dumpy level, you need to first set up the level on stable ground. Then, adjust the bubble to ensure it is accurately leveled. Finally, using the leveling screws, make small adjustments to bring the crosshairs into alignment with a known benchmark or datum point.
i honestly dont know
A dumpy level consists of a telescope, bubble level, crosshairs, and leveling screws. The telescope is used to sight objects, the bubble level ensures the instrument is level, the crosshairs help with accurate targeting, and the leveling screws are used to adjust the instrument for precise measurements.

AIM/PURPOSE: To describe the instruction for the calibration of Dumpy Level to ensure that equipment is maintained in fully serviceable condition, is safe to operate and meets environmental requirements. FOR THE CALIBRATION OF DUMPY LEVEL The method described below is to be used on-site check prior to use as to the accuracy of the Dumpy level between calibration checks. This Work instruction shall be conducted at the commencement and completion of a contract. 1. Drive two pegs, "A" & "B", into the ground six metres or more apart 2. Set Dumpy up at "C" 3. Shoot a level at "A" and "B" 4. Relocate Dumpy to "D" and shoot a level at "A" and "B" 5. Record the appropriate result in the workbook. (Levels shot at "D" should be within ± 10mm of "C") D A C B
First take the dumpy level to the place of surveying and place the tripod on the ground. Make sure that the three points of the tripod is placed such that the observer can take readings quite easily. Then take the dumpy level and place it on tripod and fix the center nut and make sure that the dumpy level doesn't shake. Then check the bubble level in the dumpy level and use adjust the main level screw so that at least 2/3 of the bubble is inside the circular area of the bubble level. Then adjust it by the other two screws and rotate the dumpy level 90 degrees and check whether the bubble shows a leveled stage. If it shows that the bubble is centered then it is O.K the dumpy level is leveled..... Then in order to take a reading, the u bubble should have to be leveled adjust the screw in the right side(there are a few adjusting screws,please get to know the actions performed by the screws, for that we must handle the instrument for sometime) and make sure the 'U' shape is formed. Now the instrument is ready take readings.....
A dumpy level (or spirit level) is used to establish the height difference between two measured points; or can be used to establish points (over an area/ or horizontal plane) which have the same height.Dumpy levels have been replaced by more modern laser leveling devices, but are still used extensively in the construction industry as they are cheap and easy to use (although not as accurate as laser levelers).Dumpy level
