It typically consists of a series of uniformly spaced marks or graduations, which are read by the surveyor using a surveying instrument, such as a level or a theodolite.

Q2: How do you read a levelling staff?
A2: A staff reading consists of 4 digits. The first digit represents the whole number of meters, the second digit represents decimeters, and the third, and fourth digits represent millimeters.

Tips: How to use leveling staff?

A leveling staff is a measuring instrument used in surveying and construction to determine height differences and elevations between different points. Here's how to use it:

• Choose a suitable location. Choose a location that provides a clear line of sight to the other points you want to measure. Make sure the location is stable and level.
• Set up the leveling staff. Place the leveling staff at the point you want to measure the elevation.
• Position the level. Position the level so that it is level and stable. Use the leveling screws to adjust the level if necessary.
• Take the initial reading. Look through the level and take a reading of the height of the staff at its base.
• Move to the next location. Move the level to the next location you want to measure. The new location should be within sight of the previous location.
• Take a reading. Look through the level and take a reading of the height of the staff at its base at the new location.
