SELF-REDUCING SET NUT

SELF-REDUCING Autor ducteur: Topography

Of a topographic instrument which functions according to the following principle: to measure an AB distance on the ground, we place a leveling self-reading (leveling) rod in B, held vertically, and a stadiameter in A. The optical axis of our telescope should be directed following two successive inclines whose p ? - p difference in slope we can measure. The readings of the leveling staff are performed in B and C; i.e., x length BC, we have:

The reduced length to the horizon is:
