ZA = Line of sight / collimation axis
Telescope axis = line from the reticle to the
center of the objective.
SA = Standing axis
Vertical rotation axis of the telescope.
KA = Tilting axis
Horizontal rotation axis of the telescope.
Also known as the Trunion axis.
V = Vertical angle / zenith angle
VK = Vertical circle
With coded circular division for reading the
vertical angle.
Hz = Horizontal direction
HK= Horizontal circle
With coded circular division for reading the
horizontal angle.

Direction of gravity. The compensator defines the plumb line
within the instrument.
TS0X_003
Angle between plumb line and standing axis.
Standing axis tilt is not an instrument error and is not eliminated
by measuring in both faces. Any possible influence it may have on
the horizontal direction or vertical angle is eliminated by the dual
axis compensator.
TS0X_004
Point on the plumb line above the observer.
TS0X_070
Glass plate within the telescope with reticle.
TS0X_071
The line-of-sight error (c) is the deviation from the perpendicular
between the tilting axis and line of sight. This could be eliminated
by measuring in both faces.
