Tip – When you use the prism at a short distance, set the prism at a slight angle to the sighting
axis, rather than completely square.
Reflector prisms
When measuring distances using reflector prisms, a prism needs to be placed at the target place.
Reflector systems come with single prism and triple prisms, which can be mounted in a tribrach onto
a tripod or mounted onto a prism pole. Reflector systems can be self-configured by users according
to the job.
Mounting and dismounting the instrument
from the tribrach
Dismounting
If necessary, the instrument (including reflector prisms with the same tribrach) can be dismounted
from the tribrach. Loosen the tribrach locking screw in the locking knob with a screwdriver. Turn the
locking knob about 180°counter-clockwise to disengage anchor jaws, and remove the instrument
from the tribrach.
