Basic Operation
Using a Fiber Holder
1. Open the lid of a fiber holder and then set the fiber onto the fiber holder.
2. Adjust the positon of fiber and then close the lid of fiber holder. The position of the fiber is
dependent on the fiber holder as shown below.
In case of Fiber holder “
FH-60 series
”;
Set the fiber onto the fiber holder with the fiber sheath
3mm
from the edge of the fiber
holder.
In case of Fiber holder “
FH-70 series
”;
Use either the edge, or the extruded fiber support of the fiber holder as the reference
point. Adjust the position of the sheath edge as follows:
If the reference point is set as the edge of the fiber holder, set the fiber onto the
fiber holder with the fiber sheath
3.0mm
from the edge of the fiber holder.
If the reference point is set as the extruded fiber support of the fiber holder, set the
fiber onto the fiber holder with the fiber sheath
1.5mm
from the extruded surface of
the fiber holder.
Select a suitable fiber holder based on the fiber coating diameter.
If fiber coating has some memory curl, place fiber so that the curve of memory
is turned downwards.
Close the lid of a fiber holder while pressing down with a finger on the coating
(refer to figure below).
