What is Inverted Staff Readings in Surveying about?

This document discusses two additional levelling methods: inverted staff readings and using intermediate sights. For inverted staff readings, the staff is held upside down to determine the reduced levels of points above the line of collimation, with these readings entered with a negative sign. Calculations still consider signs to determine rises and falls correctly. Intermediate sights can be used to determine the height of an instrument but an inverted staff must not be used as a turning point.
