Notes on Use
In order to ensure safe operation and to
obtain maximum performance from the
product, observe the cautions listed below.
DANGER
･Operation of this product according to any
procedure not specified in this manual may
cause explosion due to dangerous laser
radiation.
･The 3415-02 (2-beam laser marker type product)
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.

WARNING
･To avoid electric shock, do not allow the product
to get wet, and do not use it when your hands
are wet.
･If the protective functions of the product are
damaged, either remove it from service or mark
it clearly so that others do not use it
inadvertently.
CAUTION
･ Do not use the product near a device that
generates a strong electromagnetic field or
electrostatic charge, as these may cause erroneous
measurements.
･ The product should always be operated indoors in a
range from 0℃ to 40℃(3415-02), 0℃ to 50℃(3416-
02, 3418-01) and 35% to 80% rh or less.
･ Do not store or use the product where it could be
exposed to direct sunlight, high temperature or
humidity, or condensation. Under such conditions,
the product may be damaged and insulation may
deteriorate so that it no longer meets specifications.

CAUTION
･ This product is not designed to be entirely water- or
dust-proof. To avoid damage, do not use it in a wet
or dusty environment.
･ Do not use the product where it may be exposed to
corrosive or combustible gases. The product may
be damaged or cause an explosion.
･ To avoid damage to the product, protect it from
vibration or shock during transport and handling,
and be especially careful to avoid dropping.
･ 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 product.
･ When the
mark on the display is flashing,
the batteries are low. Fit new batteries.

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
