Under some circumstances the laser
dot is not visible, for example over
pipes. In this case, the laser dot can
be made visible by using a trans-
parent plate so that the laser dot can
be easily aligned to the center of the
pipe.
If the instrument is equipped with the
optional shifting tribrach it can be
aligned to the ground point by slight
shifting.
