Warnings and Cautions
◆Please use the thermometer correctly by keeping the following items.
In addition, please read this instruction manual carefully and keep it at the place where
you can access easily.
The mark indicates prohibited operations.
Warning (May cause death or serious injury)
Don’t use the fiber optic assembly in places over 150 ºC.
Don’t operate the thermometer in places where combustible or volatile gas is existed.
It is extremely dangerous to use the thermometer in such environment.
When connecting power to the power terminals, make sure that all mains is turned off to
prevent an electric shock.
Don’t use the thermometer if it was broken, smoking or nasty smelling.
These may cause fire. For such abnormal condition, turn off the power switch at once
and contact your sales agent of CHINO Corporation.
Laser may damage your eyes. Don’t stare into a laser beam. Make sure to target the laser
when you want the decide the center of the measuring object only and to go off it after
the center of the measuring object is decided.
Never take the thermometer apart or convert it.
These may cause trouble and danger.
Caution (May cause injury or physical damage)
The thermometer has been calibrated with the fiber optic assembly. When you use several
thermometers, make sure that the combination of the thermometer and the fiber optic
assembly is correct. (Ref. [3.1.1 Thermometer view] and [3.3 Fiber optics]
The maximum working temperature of the fiber optic assembly is 150ºC. Use it under this
maximum working temperature. (Ref. [3.2 Fiber optics assembly])
Be careful not to give vibration or impact to the thermometer. Install the thermometer by
keeping it as far as possible from an inductive oscillator or electric power line.
Avoid the unnecessary detachment and attachment of the fiber optics.
Make sure not to tension the fiber optics or bend its joint to the optical connector.
(Strong tension or too bending the fiber optics may cause damage of the optical fiber.)
The fiber optics can be bent but make sure to use it with the bending radius larger than its
allowable value (R: about 100mm). (Ref to [4.3 Cautions on installation/maintenance of fiber
optics])
When connecting the optical connectors of the fiber optics to the optical connectors of the
thermometer and the lens assembly, make sure to turn them with your hand. (Don’t turn them

1. Introduction
1.1 General
In the IR-FA series fiber optic radiation thermometers, four kinds of models, single color type Models
IR-FAI and IR-FAS and two-color type model IR-FAQ and IR-FAQI, and IR-FAQH, and IR-FAQS are
available.
The thermometer, the fiber optics, and the lens assembly are connected through optical connectors. The
radiation energy collected through the lens is transmitted to the element through the optical fiber and is
converted into an electrical signal. The element output is digitally converted and processed through
emissivity compensation, linearizer, and modulation. The standardized final output is 4 to 20mA DC.
Functional keys make programming or selection of emissivity, signal modulation and alarm function easy.
Two types of the lens assembly are available, a universal type, and the lens assembly with a viewfinder.
An air purge case is available for the universal type lens assembly.

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.

the thermometer, make sure to turn it with your hand.
(Don’t turn it by using a tool like as pliers.)
Caution
The thermometer has been calibrated with the fiber optic assembly. Connect the correct fiber
optics assembly to the thermometer (Ref. [3.1.1 Thermometer view] and [3.3 Fiber optics])
If you want to use the different combination of the thermometer and the fiber optics assembly,
you are requested to return them for re-calibration.
Caution
For mounting the lens assembly with the air purge case, connect the fiber optics after mounting
the air purge case. For removing, disconnect the fiber optics and then remove the air purge
case. If the air purge case being connected with the fiber optics is mounted or removed, the
fiber optics may be damaged by the weight of the air purge case.

5.1.2 Wirings to power terminals
5.1.3 Wirings to ground terminals
5.1.4 Wirings to receiving instruments
When connecting power to the power terminals, make sure that all mains power is turned off to
prevent an electric shock.
Warning
The current output is 4 to 20mA DC and isolated.
The contact output is the open collector output (photo-coupler).
Use a receiving instrument under the ratings (30V, 50mA).
Reference
Caution
Provide a low impedance earth ground (lower than 100Ω) connection to the ground terminal.
The use of the power unit IR-ZFEP is recommended. Use a Class 2 power supply (24V DC)
when you don’t use the IR-ZFEP and use cords of 0.14 to 24mm2 for wiring.
