3Collimate the 2nd target (B).
The required V/H angle to target B will be
displayed.
Collimate B
Reference : How to Collimate
1Point the telescope toward the light. T urn the diopter ring and adjust the diopter so that the cross
hairs are clearly observed.
(Turn the diopter ring toward you first and then backward to focus.)
2Aim the target at the peak of the triangle mark of the sighting collimator. Allow a certain space
between the sighting collimator and yourself for collimating.
3Focus the target with the focusing knob.
*If parallax is created between the cross
hairs and the target when viewing
vertically or horizontally while looking
into the telescope, focusing is incorrect
ordiopter adjustment is poor. This
adversely affects precision in
measurement or survey Eliminate the
parallax by carefully focusing
and using diopter adjustment.
