4.3 Cautions on installation/maintenance of fiber optics
4.4 Confirmation of view field
The lens assembly has no viewfinder. If an object is small, there is a possibility of the lack of the view
field. Therefore it is necessary to confirm the view field to avoid the measurement error.

Notice
Notice
Don’t use the fiber optics through water or oil.
Caution
When connecting the optical connectors of the fiber optics to the optical connectors of the
thermometer and the lens assembly, make sure to connect them by turning with your hand.
Don’t turn them by using a tool like as pliers to prevent their damage.
Caution
The allowable bending radius of the fiber optics is about 100mm.
The optical fiber may be damaged if it is bent smaller than the radius of 100mm. Especially,
be careful that its joint part to the lens assembly or the thermometer may be easily bent.
Caution
For connecting the fiber assembly to the thermometer, align the pin of the optical connector of
the fiber optic assembly with the key slit of the optical connector of the thermometer, and then
push the fiber optic assembly. Confirm that the pin is placed in the key slit by lightly turning
the metal part of the fiber optic assembly and them fix the fiber optic assembly to the optical
connector of the thermometer by turning the hexagon cap nut by hand.
(Ref.[5.1 Connections/Wirings].)
Don’t damage the fiber optics edge face or make it dirty.
Caution
!
Be careful that the maximum working temperature of the fiber optics assembly is 150°C
.
Warning
Laser may damage your eyes. Don’t stare into a laser beam.
Warning
Confirmation method of view field
(1) With the object heated up, move the lens assembly in all directions slightly to confirm
the indicated temperature value will not change largely. (On the condition that the view
field is lacked, the indicated temperature value will change largely if the view field is
slightly moved. However, for Model IR-FAQH with two-color processing, this method
cannot be applied because the indicated temperature value may not change largely.
(2) Confirm the view field by using a laser targeting function (option).
As the laser is targeted to an object through the fiber optics assembly, it is very easy to
confirm the view field.
