Equipment -Dumpy level machine
A **dumpy level** (also called a **spirit level** or **surveying level**) is a tool used in construction, surveying, and civil engineering to measure or establish **horizontal levels** and elevations. It consists of a telescope mounted on a tripod with a built-in **spirit level** or **bubble level** to ensure proper alignment. ### How a Dumpy Level Works: 1. **Set Up the Instrument**: The dumpy level is mounted on a tripod at a desired location, typically in the center of the area to be measured. 2. **Adjusting the Level**: The instrument is adjusted to ensure it is perfectly horizontal by using the spirit level. The bubble inside the vial is centered, indicating the dumpy level is perfectly horizontal. 3. **Using the Telescope**: The operator looks through the telescope to focus on a **staff** or **rod** placed vertically at a known reference point. The staff typically has graduated measurements, allowing the operator to read the height difference between points. 4....
