Measuring distances

Working with the level

1.  Place the level as close as possible 

      to the mid-point between 

      2 measuring points and level the 

      instrument.

2. Align the level with measuring 

    point A and read off the figure A1.
3. Align the level with measuring 

    point B and read off figure B1.

∆h = A1-B1

Example:

∆h = 2,218 m - 1,950 m = 0,268 m
