6 Stereo measurement procedures (RX (stereo measurement function) only)
See also "3.3 Pre-operation/post-operation inspections" (P. 25) for more information on attaching
stereo optical adapters.
6.2 Attaching the stereo optical adapter
1
Make sure that the O-ring in the distal end is properly attached.
2
Attach the adapter so that there is no movement of the adapter main body.
Rotate the optical adapter in the direction of the arrow A shown in the figure.
Keep the adapter rotated completely and turn the nut of the optical adapter in
the direction of the arrow B shown in the figure until it is tight.
●
Tools or excessive hand force should not be used to secure the tip adapter to the distal end.
●
Make sure that the stereo optical adapter is attached properly without loose and without dirt or dust.
●
If the attached optical adapter rattles or is loose, or even though it does not rattle or is not loose, if it is not
firmly attached completely by rotating in the direction of arrow A shown in the picture, the measurement
accuracy deteriorates.
●
After installation of the optical adapter, if the distal end is handled by grasping the optical adapter, it may
turn in the opposite direction of arrow A in the figure even when the nut is tightened securely. This could
result in lowered measurement accuracy.
When handling the distal end, do not hold it by the optical adapter, always grasp the insertion tube. How-
ever, do not hold it by the angulation section.
●
When the insertion tube's distal end is subjected to a large extraneous force or vibration, the optical
adapter installation may be jolted, loosened or turned. Even if you leave the optical adapter attached to the
insertion tube, always check the installation condition before inserting the insertion tube into the observa-
tion measurement area.
