1 Introduction
Thank you for purchase of the IR Thermometer. This is capable
of non-contact (infrared) temperature measurements at the touch of
a button. The built-in laser pointer increases target accuracy while
the backlight LCD and handy push-buttons combine for convenient,
ergonomic operation.
The Non-contact Infrared Thermometers can be used to
measure the temperature of objects’ surface that is improper to be
measured by traditional (contact) thermometer (such as moving
object, the surface with electricity current or the objects which are
uneasy to be touched.)
Proper use and care of this meter will provide years of reliable
service.
In the present manual we apply three kinds of warnings. These
are texts in frames, which describe possible dangers both for the
user and the meter itself. The messages starting from the word
‘WARNING:’ describe situations which imply a risk for life or health
should the recommendations presented in the present manual not
be observed. The word ‘ATTENTION!’ introduces a description of a
situation where non-observance of the recommendations presented
in the present manual may imply damage for the meter. Indications
of possible problems are preceded by the word ‘Attention:’.
WARNING:
Before using the instrument acquaint yourself with the
present manual and observe the safety regulations and
recommendations specified by the manufacturer.

obtained results it is necessary to observe the following recom-
mendations:
•Use extreme caution when the laser beam is turned on.
•Do not let the beam enter your eye, another person’s eye or the
eye of an animal.
•Be careful no to let the beam on a reflective surface strike your
eye.
•Do not allow the laser light beam impinge on any gas which can
explode
•It is prohibited to operated the meter:
⇒If it is damaged and completely or partially out of order
⇒If it has been stored for an excessive period of time in
inadequate conditions (e.g. if it is humid)
•Before commencing a measurement make sure the correct
measurement function has been selected,
•Repairs must be realised solely by an authorised service
workshop

6 How it Works
How it Works
Infrared thermometers measure the surface temperature of an
object. The unit’s optics sense emitted, reflected, and transmitted
energy, which is collected and focused onto a detector. The unit’s
electronics translate the information into a temperature reading,
which is display on the unit. In units with a laser, the laser is used
for aiming purposes only.
Field of View
Make sure that the target is larger than the unit’s spot size. The
smaller the target, the closer you should be to it. When accuracy is
critical, make sure the target is at least twice as large as the spot
size.

12
Distance & Spot Size
As the distance (D) from the object increases, the spot
size (S) of the area measured by the unit becomes larger.
See: Fig: 1.
Locating a hot Spot
To find a hot spot aim the thermometer outside the area
of interest, then scan across with an up and down motion until
you locate hot spot.
Reminders
①Not recommended for use in measuring shiny or polished
metal surfaces (stainless steel, aluminum, etc.). See
Emissivity.
②The unit cannot measure through transparent surfaces
such as glass. It will measure the surface temperature of the
glass instead.
③Steam, dust, smoke, etc., Can prevent accurate
measurement by obstructing the unit’s optics.
Emissivity

13
Emissivity is a term used to describe the energy-emitting
characteristics of materials.
Most (90% of typical applications) organic materials and painted
or oxidized surfaces have an emissivity of 0,95 (pre-set in the unit).
Inaccurate readings will result from measuring shiny or polished
metal surfaces.
To compensate, cove the surface to be measured with masking
tape or flat black paint. Allow time for the tape to reach the same
temperature as the material underneath it. Measure the
temperature of the tape or painted surface.
Emissivity Values
Substance Thermal
emissivity Substance Thermal emissivity
Asphalt 0,90 to 0,98 Cloth (black) 0,98
Concrete 0,94 Human skin 0,98
Cement 0,96 Leather 0,75 to 0,80
Sand 0,90 Charcoal (po-
wder) 0,96
Earth 0,92 to 0,96 Lacquer 0,80 to 0,95
Water 0,92 to 0,96 Lacquer (matt) 0,97
Ice 0,96 to 0,98 Rubber (black) 0,94
Snow 0,83 Plastic 0,85 to 0,95

7 Measurement operation
•Hold the meter by its Handle Grip and point it toward the
surface to be measured.
•Pull and hold the Trigger to turn the meter on and begin
testing. The display will light if the battery is good. Replace the
battery if the display does not light.
•While measuring, the SCAN display icon will appear in the
upper left corner of the LCD.
•Release the Trigger and the HOLD display icon will appear on
the LCD indicating that the reading is being held. In HOLD
status, press the Laser/Backlight button to turn on or off the
laser and the backlight.
•The meter will automatically power down after approximately 7
seconds after the Trigger is released. (Unless the unit is
locked on.)
How to obtain Emissivity?
In the EMS mode, press and hold the Trigger and in the same
time press the Laser/Backlight button twice: once short and second
one longer until the EMS icon on the left side of LCD blinking. At
this time, “ε= --” will appear at the upper side of the LCD; IR
temperature value will be in the middle of LCD; and Type K
temperature value is at the lower side of the LCD.
Contact the Type K probe to the object surface and test the
temperature of same point with IR measurement. After both values
are stable, press UP or DOWN button for confirmation. Then,
emissivity of the object will be shown at the upper side of the LCD.
Press MODE button or trigger to enter normal measurement.
Note:
1. When the IR value is not corresponding to the TK value, or IR
and TK tested the different points, no emissivity will be
obtainable or a wrong emissivity will be obtained.
2. The temperature of the target should be higher than the

15
environment temperature. Normally, 100°C is suitabl e for
obtaining a higher accuracy emissivity.
After obtaining the emissivity, if the difference between IR value
(in the middle of LCD) and TK value (at the lower side of LCD) is
too big, the obtained emissivity will be incorrect. It’s necessary to
obtain a new emissivity.
Note: Measurement considerations
Holding the meter by its handle, point the IR Sensor toward the
object whose temperature is to be measured. The meter
automatically compensates for temperature deviations from ambient
temperature. Keep in mind that it will take up to 30 minutes to adjust
to wide ambient temperatures are to be measured followed by high
temperature measurements, some time (several minutes) is
required after the low (and before the high) temperature
measurements are made. This is a result of the cooling process,
which must take place for the IR sensor.
8 Data Logger
8.1 Storing Data
Your thermometer is capable of storing up to 20 data locations.
The infrared temperature and temperature scale (
o
C or
o
F) are also
stored.
To store data from an infrared reading, pull the trigger. While
holding the trigger, press the MODE button until LOG appears in
the lower left corner of the display; a log location number will be
shown. If no temperature has been recorded in the shown LOG
location, 4 dashes will appear in the lower right corner. Aim the unit
at the target area you want to record, and press the laser/backlight
button. The recorded temperature will appear in the lower right
corner. To select another log location, press the up and down keys.

16
8.2 Recalling Data
To recall stored data after the unit shuts off, press the MODE
button until LOG appears in the lower left corner. A LOG location
number will be shown below LOG, and the stored temperature for
that location will be display. To move to another LOG location,
press the UP and DOWN keys.
8.3 Log Clear Function
The “Log clear” function allows you to quickly clear all logged
data points. This function can only be used when the unit is in LOG
mode. It can be used when the user has any number of LOG
locations stored.
You should only use the LOG clear function if you want to clear
all the Log location data that is stored in unit’s memory. The “LOG
clear” function works as follows:
(1) While in LOG mode, press the Trigger, and then press the
DOWN button until you reach LOG location “0”.
Note: This can only be done when the Trigger is pulled. LOG
location “0” cannot be accessed, by using the UP button.
(2) When LOG location “0” shows in the display, press the
Laser/Backlight button. A tones will sound, and the LOG location
will automatically change to “1”, signifying that all data locations
have been cleared.
9 Battery Replacement
①As battery power is not sufficient,
LCD will display “ ” replacement
with one new 9V battery is
required.
