explain the essential difference between the dumpy level and tilting level.state under what circumstances each is used
Answers
Answer:
DUMPY LEVEL
What makes a dumpy level appealing to many surveyors is its simple, straightforward design and relative lack of moving parts. Compared to an automatic level, a dumpy level is easier to manipulate but requires more precision from the surveyor. Surveyors will not need to make as many adjustments to a dumpy level as they would to an automatic level, as dumpy levels can retain adjustments for a longer period of time.
Like automatic levels, dumpy levels require support from a tripod that is raised to eye level. Dumpy levels feature high optical power that allows for accurate, reliable long-range readings.
AUTO LEVEL
Because automatic levels are higher-tech in their design, there can be a learning curve to using them effectively. However, surveyors who take the time to understand all the features and SSW the full capacity of their auto level will find it easier to use. Auto levels are known for their high standard of accuracy, and while dumpy levels can also measure angles quite accurately, they require more input from the operator to achieve this standard of precision.
Auto levels contain an internal compensator mechanism that intuitively adjusts the line of sight to ensure accuracy. You can also adjust the position of the level’s sight bubble using the screws on any side of the device
