Safety Notes
CAUTION
Incorrect measurement procedures could result in
injury or death, as well as damage to the equipment.
Please read this manual carefully and be sure that
you understand its contents before using the
equipment. The manufacturer claims no liability for
any damage caused by this system except for
damage resulting from a defect in the system itself.
This manual contains information and warnings
essential for safe operation of the product and for
maintaining it in safe operating condition. Before
using the product, be sure to carefully read the
following safety notes.
Safety symbols
In the manual, the symbol indicates
particularly important information that the
user should read before using the
product.

Measurement categories (Overvoltage
categories)
To ensure safe operation of measurementproducts,
IEC 61010 establishes safety standards for various
electrical environments, categorized as CAT I to
CAT IV, and called measurement categories. These
are defined as follows.
CAT I: Secondary electrical circuits connected to an
AC electrical outlet through a transformer or
similar device.
CAT II: Primary electrical circuits in equipment
connected to an AC electrical outlet by a
power cord (portable tools, household
appliances, etc.)
CAT III: Primary electrical circuits of heavy
――――――――――――――――――――――――

iv
―――――――――――――――――――――――――――
equipment (fixed installations) connected
directly to the distribution panel, and feeders
from the distribution panel to outlets.
CAT IV: The circuit from the service drop to the
service entrance, and to the power meter and
primary overcurrent protection device
(distribution panel).
Higher-numbered categories correspond to electrical
environments with greater momentary energy. So a
measurement device designed for CAT III
environments can endure greater momentary energy
than a device designed for CAT II.
Using a measurement product in an environment
designated with a higher-numbered category than
that for which the product is rated could result in a
severe accident, and must be carefully avoided.
Never use a CAT I measuring product in CAT II,
III, or IV environments.
The measurement categories comply with the
Overvoltage Categories of the IEC60664 Standards.

Notes on Use
Follow these precautions to ensure safe operation
and to obtain the full benefits of the various
functions.
WARNING
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 electric shock, do not allow the
product to get wet, and do not use it when your
hands are wet.
CAUTION
To avoid system damage and malfunction by
making sure that the object to be measured does
not touch the system.
Do not touch the lens with a hard object, apply
undue pressure to the lens, or insert a foreign
substance in the unit. These actions will cause
system damage or malfunction.
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 touch the LCD screen surface, since doing
so may cause erroneous display or distortion.

CAUTION
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 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.
This product is designed for indoor use, and
operates reliably from 0
to 40 .
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 near a device that
generates a strong electromagnetic field or
electrostatic charge, as these may cause
erroneous measurements.
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.
Do not disassemble or modify the system, since
doing so may prevent the system from satisfying
the specifications.
――――――――――――――――――――――――
Notes on Use
―――――――――――――――――――――――――――
NOTE
Accurate measurement may be impossible in the
presence of strong magnetic fields, such as near
vii
transformers and high-current conductors, or in the
presence of strong electromagnetic fields such as
near radio transmitters.
If the set emissivity differs from the emissivity of
the object, a measurement error may result.
To avoid corrosion from battery leakage, remove
the batteries from the product if it is to be stored
for a long time.
To avoid problems with battery operation, remove
the batteries from the product if it is to be stored
for a long time.

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 3460-50 2D THERMO HiTESTER, 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 8μm cuton
filter, etc..
1
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.
1.2 Characteristic
Measures two-dimensional temperature using the
thermopile array (8 x 8 elements)
Equipped with a 3.8-inch color LCD
Built-in CMOS camera enables simultaneous display
of temperature image and optical image on a screen.
Compact and lightweight
Data stored on a compact flash card
The temperature alarm helps detect abnormal
temperatures.
Provided with an NTSC video terminal; images can
be recorded on a video recorder (video cable
available as an option).
Logging function and alarm function are available.
Temperatures can be recorded, monitored, and
alarms sent by connecting to a PC and creating a
program. (Interface cable is supplied separately.)

WARNING
To avoid damage, turn the product off before
connecting the AC adapter to the product and
to AC power.
Use only the AC adapter supplied with Model
3915 OPTION PACK. AC adapter input voltage
range is 100 to 240 VAC (with 10% stability) at
50/60 Hz. To avoid electrical hazards and
damage to the product, do not apply voltage
outside of this range.
Make sure the power is turned off before
connecting or disconnecting the AC adapter.
NOTE
To ensure proper system operation, do not use the
AC adapter with an unstable power supply. In
particular, be careful about the mixing-in of impulse
components.
