1-2 Applications
Thank you for purchasing this infrared thermometer.
The Infrared Thermometer is a non-contact infrared
temperature measuring instrument. To measure a
temperature, point the unit at the object until the
temperature is read, pull the measuring trigger and
hold.Make sure the target area is larger than the unit's
spot size. For large target objects assure you are within
target distance.
1.Product Introduction
Read the following safety information carefully
before attempting to operate or service the meter.
Only qualified personnel should perform repairs or
servicing not covered in this manual.
2.Safety Information
2Gun-Type ProfessionalInfrared Thermometer
DO NOT submerge the unitin water.
This product is not designed for use in medical
evaluations. The product can only be used to
measure body temperature simply for reference.
They are meant for industrial and scientific
purposes.
2-1 Cautions!
2-2 Safety symbols
Dangerous, refer to this manual before using
the meter.
CE Certification.
Laser Warning Note!
Do not point laser directly at eye. Use
caution a round reflective surfaces. Keep out of
reach of children.
This instrument conforms to the followingstandards:
EN61326:Electrical equipment for measurement,
control and laboratory use.
IEC61000-4-2:Electrostatic discharge immunity test.
IEC61000-4-3: Radiated, radio-frequency,
electromagnetic field immunity test.
IEC61000-4-8: Power frequency magnetic field
immunity test.
Tests were conducted using a frequency range of 80-
1000MHz with the instrument in three orientations. The
oo
average error for the three orientations is 0.5 C ( 1.0 F) at
3V/m throughout the spectrum. However, between 781-
1000MHz at 3V/m, the instrument may not meet its stated
accuracy.

4.Operation of Instrument
4 Gun-Type ProfessionalInfrared Thermometer
To measure a temperature, point the unit at the
target you want to measure, pull the trigger and
hold. In SCAN mode, the LCD displays the
current temperature inCelsius or Fahrenheit. The
unit will HOLD the last reading for about 6
seconds after the trigger is released; the word
HOLD appears. Be sure to consider the target
area inside the angle of vision of this instrument.
The laser is used for aiming only. For small
targets at short distances the aim should be
adjusted respectively.

4-3 C/ F and Battery Change
The unit is powered by 9V
battery and displays
temperatures in either C
or F. The user has to
replace the battery when
the battery voltage drops
below the voltage for
reliable operation and at
the same time the low
battery symbol will
appear.
To change the 9V battery,
pull open the unit's handle
under the trigger. After
replacing the battery push
back and snap in place.

5.Techniques Of Infrared
Thermometer
The field of view is the angle of vision at which the
instrument operates, and is determined by the
optics of the unit. The FOV is the ratio of the
distance from the target to the target diameter. The
smaller the target, the closer you should be to it.
When the target diameter is small, it is important to
bring the thermometer closer to the target to insure
that only the target is measured.
