Reference
The emissivity ratio is the rate of the energy emitted from the surface of the object.
All objects possess a particular emissivity ratio which changes according to the
object's surface conditions or temperature.
Our thermometer allows the emissivity ratio to be set at a fixed rate, enabling the
surface temperatures of the following objects to be almost precisely measured
0.95(DARK)…rubber, plastic, paper, food, painted surfaces, etc.
0.70(BRIGHT)… oxidized metallic surfaces, etc. can be measured correctly.
In the case of objects with different emissivity ratios than the objects listed above,
deviation of measurement will occur. In such cases, take their figures as approxi-
mate values by placing our separately sold black tape (ε=0.95) onto the object to be
measured, the object can be almost precisely measured.
Conformance to EU Directives
• This in a class A product. In residential areas it may cause radio interference, in
which case the user may be required to take adequate measures to reduce
interference.

Thank you very much for purchasing this product. This device is a non-con-
tact thermometer to convert the infrared energy emitted from the surface of
an object into temperature. This thermometer measures the surface
temperature of solid and liquid without contacting them. The temperature of
gas cannot be measured by this thermometer.
This instruction manual contains various warnings for your safety and proper
usage to avoid possible personal injury. Please be sure to heed the
warnings and strictly follow safety instructions.
Do not look into the laser beam, nor point it
directly at eyes. Even the reflection is harmful.
This laser may cause eye injury or damage to
your health.

This symbol signifies that improper usage may
result in injuries or damage.
Use of controls or adjustments or performance
of procedures other than those specified herein
may result in hazardous radiation exposure.

1) Do not throw used batteries into a fire. Do not recharge them.
2) Follow the local laws or regulations when disposing the batteries.
3) Take the batteries out of the thermometer when you do not use for a long time.

KEEP THE THERMOMETER
AWAY FROM DROPPING
WATER AND DO NOT USE IN
WATER.
This thermometer is not water-
proof.
DO NOT APPLY SUDDEN
TEMPERATURE CHANGES
TO THE THERMOMETER.
Sudden temperature changes
may cause incorrect measuring
results in such cases, leave the
thermometer for a moment to
let it retain to a stable condition
prior to the next measurement.
KEEP THE THERMOMETER
AWAY FROM PRODUCTS
WHICH PRODUCE STRONG
ELECTROMAGNETIC
WAVES.
Usage in such environments
will cause irreparable damages
to the unit and in-correct
measurements.
KEEP THE THERMOMETER AWAY
FROM DIRECT SUNLIGHT, DUST,
HIGH TEMPERATURES AND HIGH
HUMIDITY DURING USE AND STO
RAGE.
Otherwise, the optical lens will
become dirty or damaged. Such
usage or storage will result in
incorrect measurement.
AVOID MEASURING SHINY
OBJECTS.
Shiny objects reflect surrounding
infrared energy.
Therefore, it results in incorrect
measurement.
DO NOT USE WITH NON-
STANDARD VOLTAGE.
Otherwise, irreparable
damages or incorrect
measurement will result.
DO NOT TOUCH THE FILTER.
Hands off the filter otherwise
measuring error might come.
KEEP THE THERMOMETER
AWAY FROM HIGH-TEMPERA
TURE OBJECT.
This may cause irreparable
damage or incorrect measurement.
DO NOT TOUCH TO THE OBJECT
THAT IS BEING MEASURED.
The unit is a non-contact thermo-
meter. Touching the unit to objects
with high temperatures will result
in irreparable damages in the
shape of the unit and incorrect
measurements.
DO NOT DROP THE THERMO
- METER OR APPLY VIOLENT
SHOCKS.
Otherwise, irreparable damages
or incorrect measurements will
result.
DO NOT USE NEAR OBJECTS
ELECTRICALLY CHARGED.
Otherwise, irreparable damages
or incorrect measurements will
result.
Usage Warnings / Cautions –– Warning –– Caution
Solution Cause Problems
Dust, dirt and scratches on the filter cause incorrect measurements. In
case of dirty filter please remove the dust on the lens with a blower etc. for
lens cleaning use.
The main unit is made of ABS. When it becomes dirty, lightly wipe with a
soft cloth which has been soaked in soapy neutral and then well wrung. Do
not apply chemical solvents such as thinner, benzine and alcohol to
remove them since these chemicals may cause erosion of the casing
surface, or disappearance of printed characters.
We recommend that you check the calibration once a year.
Please inquire at your local dealer for service.
If the above solutions do not correct the problems, the thermometer might be defective.
In this case, please contact your local dealer for service.
Axis of the laser is located 20mm left from the optical axis.
The size of the object to be measured must be sufficiently bigger than the measuring
area shown in the above illustration.

Clean the filter referring to the
maintenance clause of this manual.
Make sure target size and distance
referring Field of View chart.
Leave the unit to get it familiar with
surrounding temperature.
An error in reading is inevitable.
Use another optex thermometer
with variable emissivity system.
Wipe to clean the hole.
Cover such heat source.
