Read the stadia intercept first, then sight anywhere on the rod and record the reading. 1 1. As an alternative, an auxiliary scale, the Beaman stadia arc, can be. A specially graduated arc attached to the vertical circle of an alidade or transit to simplify computing elevation difference for inclined stadia sights.
