Technical terms and abbreviations
Backsight/Foresight/
Intermediate sight
For determining the height
difference (∆H) between the
ground points A and B the back
sight (R) is measured first
followed by the forward sight
(V). Additional points relating to
A are measured as intermediate
sight (S).
Plumb line
By centring the circular level the
instrument is nearly levelled up.
A small instrument tilt remains
(the vertical axis tilt).
Compensator
The compensator in the
instrument is responsible for
compensating the vertical axis
tilt enabling an exactly horizontal
aiming.
