Notes on Use
――――――――――――――――――――――――
DANGER
･Operation of this unit according to any
procedure not specified in this manual may
cause explosion due to dangerous laser
radiation.
･The 3443-01 (field type unit) uses as a light
source a semiconducting laser which emits
visible light, and which conforms to JIS
standard class 2 (JIS C6802). (Wavelength
670nm, maximum power output 1 mW)
Since there is considerable danger of this laser
light causing damage to the eyes, be very
careful not to direct this laser light into your
eyes or those of another person.
･Do not look directly into the laser light from the
optical system.
･When measuring the temperature of an object
which has a mirror finish, be careful not to allow
the laser light beam to be reflected off the
surface into your eyes or those of another
person.
･Do not allow the laser light beam to impinge
upon any gas which can explode.
Notes on Use
In order to ensure safe operation and to obtain
maximum performance from the unit, observe the
cautions listed below.

vi
―――――――――――――――――――――――――――
Notes on Use
――――――――――――――――――――――――
WARNING
･To prevent electric shock, do not allow the unit
to become wet and do not use the unit when
your hands are wet.
･Ensure that protective functions are fail-safe:
that is to say, that if they fail they either prevent
the unit from operating or give an indication to
prevent unwitting operation.
CAUTION
･Do not use the unit near any device which
generates strong electromagnetic radiation or near
a static electrical charge, as these may cause
errors.
･The unit should always be operated indoors in a
range from 32 to 104 (0℃to 40℃) and 35% to
85% RH or less. Do not use the unit in direct
sunlight, dusty conditions, or in the presence of
corrosive gases.
･Do not store or use the unit where it will be
exposed to direct sunlight, high temperatures, high
humidity, or condensation. If exposed to such
conditions, the unit may be damaged, the insulation
may deteriorate, and the unit may no longer satisfy
its specifications.

―――――――――――――――――――――――――――
Notes on Use
――――――――――――――――――――――――
CAUTION
･This unit has been constructed with some degree of
water resistance, but if it is subjected to direct
contact with water for a long period of time, water
may get into the unit. Further, water drops left on
the lens will cause measurement errors. Wipe off
any water drops promptly.
･Do not use the unit where it may be exposed to
corrosive or explosive gases. The unit may be
damaged, or explosion may occur.
･To avoid damage to the unit, do not subject the
equipment to vibrations or shocks during transport
or handling. Be especially careful to avoid dropping
the equipment.
･Do not point the lens at the sun or at any other
source of strong light. If you do, the sensor may be
damaged.
･Do not contact the lens against the object whose
temperature is to be measured, or get it dirty, allow
it to be scratched, or allow any foreign material to
adhere to it. Doing so may cause errors.
NOTE ･Before use, verify that no damage has occurred due
to careless storage or transport, and check the
appearance and operation of the unit.
･When the mark on the display is flashing, the
battery are low. Fit new battery.

Chapter 1
Summary
1.1 Product Summary
1. Theory of Measurement
Every object emits infrared energy in accordance
with its temperature. By measuring the amount of
this radiant energy, it is possible to determine the
temperature of the emitting object.
2. About infrared
Infrared radiation is a form of light (electromagnetic
radiation), and has the property that it passes easily
through air, while it is easily absorbed by solid
matter.
With an emission thermometer which operates by
detecting infrared radiation, accurate measurement is
possible, irrespective of the air temperature or the
measurement distance.
3. Emission Thermometer Structure
Infrared radiation which has been emitted from the
object is focused upon an infrared radiation sensor,
via an optical system which includes a lens which is
transparent to infrared radiation, an 8μmcuton
filter, etc..

2
―――――――――――――――――――――――――――
Chapter 1 Summary
――――――――――――――――――――――――
The output signal from the infrared radiation sensor
is input to an electronic circuit along with the
output signal from a standard temperature sensor.
The electronic circuit calculates the object
temperature while applying standard temperature
compensation, thermal emissivity compensation,
etc., and displays the result.

Infrared rays from the object whose temperature is
to be measured are received here.
②Laser marker beam emission openings
The laser marker beams are emitted from here.
③Time key
Used to set the time and to check the time of stored
data.
④Parameter adjust keys
Used to change the date, time, and emissivity, and
to increase/lower the memory data No.
・▼ key: Decreases
・▲ key: Increases
If either of these Parameter adjust keys is held
down, the numerical value changes rapidly in the
appropriate direction.
⑤Clear key

data.
⑥MEAS key
Performs measurement while MEAS is being
pressed.
Measured value is held when the key is released.
There is no power switch.
Pressing the MEAS key turns ON the power. Power
is cut OFF in about 15 sec. if the key is not pressed,
except output to printer (automatic power OFF).
