How to Read a Levelling Staff
1. Hold the Staff Correctly
• Staff must be vertical (use a staff bubble if available).
• Bottom of staff placed firmly on the ground or point.
2. Look Through the Level
• Focus the telescope.
• The horizontal crosshair will intersect the staff markings.
• Read the number exactly at the crosshair.
Understanding Staff Markings
Most metric staffs are marked like this:
• Big numbers → metres (1, 2, 3, ...)
• Bold divisions → decimetres (0.1 m)
• Small divisions → centimetres (0.01 m)
• Some staffs use E-type markings for easy reading
Example of a Staff Reading
If the crosshair cuts the staff at:
• Metre = 1 m
• Decimetre = 0.3 m
• Centimetre = 5 cm
👉 Staff reading = 1.35 m
