Introduction
T105/T110-1.3.0en
Technical terms and abbreviations
ZA = Line of sight / collimation
axis
Line in space containing all object
points imaged into the graticule
centre at different distance settings
from
¥ to very near.
SA = Standing axis
Vertical rotation axis of the telescope
enables measuring of Hz-angles.
KA = Tilting axis
Horizontal rotation axis of the
telescope enables measuring of V-
angles.
V = Vertical angle / zenith angle
VK = Vertical circle
With coded circular division for
reading the V-angle.
Hz = Horizontal angle
HK = Horizontal circle
With coded circular division for
reading the Hz-angle.
Hz0 = Horizontal circle reading 0°
