3.7 Attachment and detachment of tribrach
The tribrach of R-2501DN, R-2502DN, R-2503DN, and R-2505DN can be detached from the
instrument, if required when replacing the instrument with a prism for example.
[Detachment]
First loosen the recessed screw with a screwdriver, then rotate the locking knob until the
arrow points upward, and lift the instrument up.
[Attachment]
Mount the instrument on the tribrach with the guide marks coinciding, and rotate the locking
knob until the arrow points downward.
The guide and guide mark must be fitted to attach the instrument.
When the tribrach does not need to be attached or detached or instrument is to be transported,
tighten the recessed screw with a screwdriver to fix the locking knob.
