Setting the position of the target plate
If using a single prism, make sure that the target plate is aligned with the tribrach
adapter and the prism.
To set the position of the target plate:
1. Use the two set screws supplied to attach the
target plate to the single prism holder.
2. Move the target plate within the screw holes
until the apex of the wedge pattern is aligned
with the vertical axis of the prism and the
tribrach adapter.
