Using a Surveying Dumpy Level A StepbyStep Guide
The dumpy level is an optical surveying leveling instrument consisting a telescope tube firmly secured in two collars fixed by adjusting screws to the stage by the vertical spindle. The telescope of dumpy level can rotate only in a horizontal plane. Relative elevation of different points of a surveying land is determined with dumpy level.
How To Use A Dumpy Level With Full Example
Dumpy level is commonly used leveling instrument to locate the points in same horizontal plane. It is also called as automatic level or builder's level. Elevations of different points and distance between the points of same elevation can be determined by dumpy level.
Using a Surveying Dumpy Level A StepbyStep Guide
A dumpy level is a device that can be set to a very accurate horizontal plane, allowing precise height measurements to be taken when using a measurement staff. The key principle of a dumpy level is that it is set perfectly horizontal. This allows accurate vertical measurements to be taken.

A dumpy level, also known as an automatic level or builder's level, is a tool designed to find the height of land masses. Though these devices may look intimidating or confusing, dumpy levels are fairly easy to use once you know how to set them up and what kinds of measurements they provide.

The dumpy level is used to determine the elevations of different points and distance between the points of the same elevation and to its supports in the dumpy level the telescope is fixed hence in the vertical axis, it cannot be rotated and can only rotate in the horizontal axis.

Take an accurate reading of a1 and b1 (see diagram). Next move the tripod and dumpy so that it is 2m from staff A, level and take readings a2 and b2. Perform the following calculation; b2i=a2-(a1-b1) If the result (b2i) is equal to the reading for b2 then the dumpy is calibrated. (Note: a1-b1 could be a negative, in this situation you add this.

A dumpy level (also known as a Builder's Level) is an optical instrument used to establish or check points in the same horizontal plane. It is used in archaeological surveying to measure horizontal levels, for example to demonstrate the difference in height at the top and base of a slope such as an excavated pit or a surviving earthwork.
