How to Use a Dumpy Level Like a Pro: Step-By-Step Guide

Dumpy levels, also known as engineer’s levels, are essential surveying instruments used to measure elevation, angle, and distance. The instrument is extremely precise and easy to use, and it is widely used in civil engineering and construction for a variety of tasks, including obtaining a level line of sight and calculating grade or slope. If you’re looking to become a professional surveyor, learning how to use a dumpy level like a pro is an absolute must. The following guide will provide you with step-by-step instructions on how to use a dumpy level like a pro.

Step 1: Prepare the Site

The first step in using a dumpy level is to prepare the site. This involves making sure that the area you’re surveying is clear of debris, hazards, and obstructions that could interfere with the instrument. The site should also have a level base to ensure the accuracy of your readings. If the ground is not level, you can use a spirit level to measure the elevation and make any necessary adjustments.

Step 2: Set Up the Tripod

Once the site has been prepared, the next step is to set up the tripod. The tripod is a device used to support the dumpy level while it’s in use. You will need to adjust the tripod so that it is level, and also adjust the height so that it is comfortable for you to use. Make sure that the tripod is properly secured to the ground so that it does not move or shift during use.

Step 3: Attach the Dumpy Level

Once the tripod is in place, the next step is to attach the dumpy level. The dumpy level should be securely attached to the tripod with the correct screws, and the eyepiece should be facing outwards so that it is easy to see. Make sure that the instrument is level and securely attached before proceeding.

Step 4: Adjust the Focus and Stadia

Before using the dumpy level, you should adjust the focus and stadia. The focus is the adjustment that adjusts the clarity of the image through the eyepiece, and the stadia is the adjustment that determines the amount of movement when the eyepiece is moved. When adjusting both the focus and stadia, make sure that you do so carefully and accurately to ensure accurate readings.

Step 5: Calculate the Elevation

Once you have adjusted the focus and stadia, you can now begin measuring the elevation. To do this, the dumpy level should be placed at the lowest point of the site and then adjusted until the bubble is centered on the level vial. After the bubble is centered, you can then make a note of the elevation, which can be used as a reference point for further measurements.

Step 6: Calculate the Grade or Slope

To measure the grade or slope of the land, you will need to use the dumpy level in conjunction with a clinometer. The clinometer should be attached to the eyepiece, and then you can take readings at various points along the survey site. By taking precise readings at each point, you can then calculate the grade or slope of the land. This is a crucial step for many surveying projects, and can help you determine the best way to proceed.

Step 7: Make Adjustments

Once you have finished taking all of your measurements, it is important to make any necessary adjustments. For example, if the elevation readings differ from one point to another, it may be necessary to make adjustments to ensure that the readings are accurate. Additionally, if the grade or slope readings are not as expected, you should make sure to take the necessary steps to ensure that the measurements are accurate.

Step 8: Clean and Store the Dumpy Level

The final step to using a dumpy level like a pro is to clean and store it properly. This can help ensure that the instrument is in good working condition and ready for use whenever needed. Inspect the instrument for any defects or damage, and then use a soft cloth and mild cleaning solution to wipe it down. Finally, use the correct storage containers to keep the instrument safe and secure when it’s not in use.


Learning how to use a dumpy level like a pro is an important skill for any professional surveyor. The above step-by-step guide provided you with the knowledge needed to properly use the instrument for a variety of surveys. From preparing the site to making the necessary adjustments, following the above steps will help you use the dumpy level like a pro.
