The red laser beam is coaxial with the telescope, used for no
prism ranging , and it is sent by telescope. If the instrument has
been calibrated, red laser beams will coincide with the line of
sight. External influence such as the vibration, the larger
temperature change and other factors may make laser beam and
viewing not overlap.
·
Before precise ranging, you should check whether the
direction of the laser beam is coaxial . Otherwise, it could lead
to inaccuracy .

Put the gray side of the reflector towards the instrument, and put
it 5 meters and 20 meters away. Start laser direction function.
Focus on the reflector center by the telescope crosshair center,
then check the position of the red laser point. Generally
speaking, the telescope is equipped with special filter, human
