Auto Levels / Digital Levels

Auto Level

An Auto Level/Automatic Level is an optical instrument used as a professional leveling tool used by surveyors, contractors, and builders for consistent surveying & accurate leveling every single time. An Auto Level measures differences in height between two points or determines the heights of objects or structures and can be used in a variety of applications, frequently to establish the grade of an area or subsidence monitoring.
An Auto level machine is a level with a compensator that is easy to use and can be set up quickly, which can save both time and money.

How to set up an Auto Level instrument:

  1. Make sure you have a calibrated auto level, A Tripod, and a Levelling Staff.
  2. Set up your tripod by stepping on the tripod’s legs to fix it into the ground and level it accurately, depending on the type, either roughly or accurately set to a leveled condition using foot screws (leveling screws).
  3. Attach auto level on the Tripod.
  4. Adjust the level to get the bubble in the Center position.
  5. Adjust recital until crosshairs are clear.
  6. Adjust the objective lens until the object you are sighting on is clear.
  7. Measurement generally starts from a benchmark with a known height determined by a previous survey, or an arbitrary point with an assumed height.
  8. Now your Auto Level is ready to operate.

Digital Level

A Digital Level is a precise instrument use for precise Levelling because it reduces the chance of human error when interpreting graduation marks, and a digital display ensures accurate readings. When job sites need fast and accurate height determinations, precision digital leveling equipment serves as valuable time-saving technology.

A Digital Level instrument runs on a rechargeable battery and uses a special Bar-coded staff for reading, where it uses an electronic image processing system to convert bar-coded data into elevation and distance values that are very accurate with no errors.

Advantages of a Digital Level:

  1. A Digital Level has a comparatively less chance of a Human Error, and the data recorded is usually very accurate.
  2. Topcon Digital Level is easy to set up, has a user-friendly menu, and has an easy-to-read digital display for a better experience.
  3. The measurements are usually precise and reliable due to automation.
  4. In an estimate, A Digital Level offers a fast and economic survey, which results in a 50% save in effort as claimed by manufacturers.
  5. A Digital Level is easy to operate in low light conditions and their data can be downloaded into a computer device enabling quick data reduction.
