To change the direction of the prism:

the clamp lever counter clockwise.
2. Turn the upper plate of the tribrach adapter
until the prism is facing in the required
direction.
3. Fasten the rotation clamp. To do this, turn the
clamp lever clockwise.
Setting the prism constant

Tip – To use a triple prism holder as a single prism holder, attach the prism to the center thread
of the prism holder.
2. Set the prism constant. To do this, hold down
[MSR1]
or
[MSR2]
for one second. For more
information, see Measurement settings, page 45 .
Note – The prism constant of a Nikon prism is always
0, whether it is attached to a single prism holder or a
triple prism holder.
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.
If your prism constant is not 0 mm, then directly enter the prism constant value
in the
Const field. For example, if your prism constant is 30 mm, enter
30mm
in the Const field on the instrument.
