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 almost level.
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.
The push button gives the
pendulum a slight tap to check the
functioning of the compensator.
