1. Introduction
1.1 General
IR-CAK is single color radiation thermometer.
Converting functions enabling digital temperature display and parameter programming are built-in.
It is suitable for measuring especially a low-temperature region at high speed.
Also it is suited to measurement such as metal, by short measuring wavelength.
This thermometer is the high accuracy fixed focus type that adopted the front chop method.
And this thermometer has laser targeting function for targeting to the measuring objects.
The radiation energy collected through the objective lens is transmitted to the element 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.
2 types of connection by terminals or a connector are available in this thermometer depending on a
connection cable. Various options and accessories are prepared for every kind of applications.

4. Installation
4.1 Precautions in installation
This IR-CA series radiation thermometer is a sensitive instrument.
Install it by referring to the following cautions.
4.2 Installation
Install the thermometer to a tripod, universal
head, protection case, or mounting plate etc., by
using screw holes for tripod (1/4-20UNC) or
screw holes for installation (4-M4) at the bottom
side.
Please read the operation manual for an
accessory when instilling it by using the
exclusive accessories.
●
Vibration and impacts
Vibration or impacts reduces the liability of the thermometer and causes an
unstable measurement by the targeting shake to a measuring surface.
If you install the thermometer in the place where vibration or impacts exist, its
caref
ul periodic inspection is requested.
Caution
●
Induction
The thermometer is designed for anti-induction but install it as far as possible
from an induction heating generator and power line distance factor.
: Outer circle inside
Caution
●
Optical path
Select a place for installation of the thermometer, where water-drops, dust, smoke,
steam, etc. would not enter between the thermometer and a measuring surface.
If such place cannot be selected and the affection by existence of such substances
cannot be ignored, blowing-out of such substance with air-purge is necessary.
Caution
●
Disturbance
s
to
make
indicat
ion
of measured value
higher
Select a place for installation of the thermometer, where sunlight, light of
incandescent lamp, flame, heat radiation from a high temperature substance,
etc. is not reflected to the measured surface and the cover glass of the
thermometer. When such light is reflected, higher temperature than the exact
one will be indicated. (The affect by such reflection will be great for the
measurement of low temperature.) If such place cannot be selected, shade the
thermometer or take similar precautionary measures.
Caution
Don
’
t use the thermometer in the following places.
1) Dusty place or a corrosive gas atmosphere.
2) Noisy and static electricity
3) Places where the ambient temperature is higher than 50°C or lower than 0°C.
4) Places where the ambient temperature changes abruptly, or high humid places.
5) Places where there are mechanical vibrations and impacts.
6) Places where combustible or volatile gas is existed.
Caution
●
Working
te
mperature
The working temperature of the thermometer is 0 to 50ºC. If the ambient
temperature is high or if the temperature of the thermometer exceeds the
maximum working temperature by reflection from a high temperature
substance, etc., water-cooling of the thermometer is absolutely necessary.
When the temperature of the thermometer does not exceed but closely reaches to
the maximum working temperature, water-cooling of the thermometer is
recommended for maintaining of the reliability of the thermometer.

When the laser targeting is activated, the laser light is radiated from the place
marked with (*). Make sure not to stare into a beam.
4.3.2 Focusing of laser targeting function
For the laser targeting, focus a measuring object by the procedure shown below after connections
(Ref. [5. Connections and wirings]).
(1) Open the control panel cover.
(2) Measurement starts with the display of the measurement mode
screen with a temperature value displayed in the main display part
as shown right.
(3) To activate the laser targeting, press SEL and keys
simultaneously for 2 seconds in the measurement mode
screen until “LASr” appears in the sub display.
(4) To stop the laser targeting, press SEL and keys simultaneously
for 2 seconds in the condition that “LASr” is displayed in the sub
display.
(5) “LASr” will disappear and the screen will return to the
measurement mode screen.

selection] (*)[Modulation degree programming] (*)
6) Emissivity value is changeabling.
(*): Refer to separate instruction manual [IR-CA series Software volume].
1. Do not disassemble this thermometer. If you disassemble, it causes the obstacle to
your eye because laser function is built-in.
2. Make sure to target the laser when you want to decide the center of the measuring
object only and to keep on following the above procedure when you exactly target the
laser. Any adjustment or procedure other than specified here makes you expose in
dangerous laser radiation.

8.1 Emissivity table
The emissivity are values determined by the material of object, profile of its surface, surface roughness,
oxidized or not, measuring temperature, measuring wavelength and other factors.
They are represented by the thermal radiation ratio "" when a black body furnace at the same
temperature is measured in the same wavelength band.
The emissivity "" is generally known by a value at the wavelength of 0.65µm when an optical pyrometer
is used. The emissivity changes according to the above factors even in case of the same material. Please
use the following table as a reference.
