1. Introduction
The IR-CZ series is a high temperature type infrared radiation thermometer (2-color type) using a hybrid
element converting functions enabling digital temperature display and parameter programming are
built-in. The thermometer is focusable and has long-distance factor for free installation. The response
time is 20ms suitable to on-line measurement.
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.
This instruction manual is explaining only "Hardware volume" for using high temperature type infrared
radiation thermometer (2-color type) Model : IR-CZQH correctly and safely, read the separate instruction
manual [IR-CZ series Software volume].
◆Request to the operator of the thermometer

6. Installation
6.1 Precautions in installation
This product IR-CZQH7□ is a precision instrument. Please install it on the occasion of setting with care
to the following item.
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
careful periodic inspection is requested.
Induction
The thermometer is designed for anti-induction but install it as far as possible from
an induction heating generator or power line.
Working temperature
The working temperature of the thermometer is -10 to 60ºC. 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.
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.
Disturbances to make indication 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

INST.No.INE-555-P5
-14-
6.2 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.
When you install it in the protective cases of exclusive accessories, it is necessary to install it in the
protection case after having attached a compatible attachment (model: IR-ZCZS).
Please read the operation manual for an accessory when instilling it by using the exclusive accessories.
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 60°C or lower than -10°C.
4) Places where the ambient temperature changes abruptly, or high humid places.
5) Places where there are inductive oscillator or electric power line
6) Places where there are mechanical vibrations and impacts.
7) Places where combustible or volatile gas is existed.

7. Targeting
7.1 Measuring distance and measuring diameter
The relation of the measuring distance and the measuring diameter is defined by the distance factor as
shown in the following formula.
Place the thermometer at the measuring distance computed by the above formula.
Considering the dislocation of the optical axis, take the measuring area more than 1.5 times the measuring
diameter.
7.2 Targeting of finder type
Look into the eyepiece lens and turn the eyepiece lens tube to focus the following targeting mark.
◆Upper view of main body
Measuring diameter of distance factor 200 is inner circle inside.
Measuring distance (mm) = Distance factor x measuring diameter (mm)

For the measurement of object exceeding 1500ºC, make sure to use the eyepiece
filter (Model: IR-ZCLF). However, when you feel glare on the measurement of
objects lower than 1500ºC, use the eyepiece filter (Model: IR-ZCLF).

7.3 Focusing of finder type
Focus a measuring object by turning the objective lens tube by its distance indication plate and the
distance marker.
When an objective lens tube does not turn around, you should confirm a screw for objective lens tube,
and please turn it after having loosened it when it closes.
Make sure that the measuring area should be larger than the targeting mark (Recommended area: For the
distance factor of 200 - More than 1.5 times the targeting mark), and then fix the objective lens tube by
screwing the attached screw (with a hexagon hole) into the fixing screw hole of the objective lens tube.

◆Connection of the exclusive cable (model : IR-ZCRC)
The connections are completed by simply connecting the connector of the cable (IR-ZCRC) to the
connector placed at the rear side of the thermometer.
(1) For the connection, align the slit in the connector of the cable and the key position in the connector
of the thermometer and firmly insert the cable connector, and then turn the coupling ring clockwise
until it is locked.
(2) For the disconnection, turn the coupling ring counterclockwise for releasing its locked status, and
pull the connector of the cable forward.
