4.3 Measurement Procedures
4.3.1 Temperature Measurement
•Hold the instrument by its handle, point the IR Sensor at the area
or object to measure, and press the Measurement Trigger.
•While the Measurement Trigger is kept pressed, the instrument
will continuously measure and update the display with the
temperature of the object pointed at with the IR Sensor.
•After the Measurement Trigger is released the instrument will
hold the last temperature reading for 7 seconds, then shut off
automatically.
4.3.2 Field of view or measurement target area
•To ensure accurate temperature measurements, make sure
that the target object is larger than the unit spot size, at the
measuring distance.
•The smaller the target, the closer you should be.
•For maximum accuracy, make sure that the target area is at
least twice as large as the spot size.

4.3.3 Selecting Temperature Units (°C/°F).
•Make sure the instrument is turned ON, if not press the
Measurement Trigger.
•Pressing the “°F” button will select Fahrenheit Degrees as the
temperature measurement units.
•Pressing the “°C” button will select Celsius Degrees as the
temperature measurement units.
•The temperature reading and selected measurement units will be
displayed on the LCD.
4.5 Other Functions
4.5.1 Display Hold
• The instrument will automatically hold the last temperature
reading after the Measurement Trigger has been released for
approximately 7 seconds.
4.5.2 Display Backlight
•Make sure the instrument is turned ON, if it is not, press the
Measurement Trigger.
•Pressing the Backlight ON/OFF Button, will turn the display
backlight ON or OFF.
• When the backlight is not needed, turn it off to prolong battery
life.
4.5.3 Laser Pointer
!
CAUTION: Laser Radiation is emitted
Avoid direct eye contact
• To turn the laser sight ON or OFF, press the “LASER” button,
when the unit is ON. The laser sight indicator will appear on the
display when the laser sight function is ON.
5. MAINTENANCE
5.1 Battery Replacement
• When the battery is low and needs to be replaced, the “Low Bat-
tery Warning” symbol will appear on the lower left hand side of the
display.
5.2 Cleaning
5.2.1 Lens cleaning
Debris or dirt on the lens may cause obstruction and reduce the
accuracy of the thermometer. If this occurs, either wipe the lens
with a Q-tip (moistened with water only) or blow the loose particles
off with clean compressed air. Do not use solvent on the lenses, as
it may damage the instrument.
5.2.2 Exterior cleaning
Periodically wipe the case with a soft damp cloth and mild house-
hold cleanser. Do not use abrasives or solvents. Ensure that no
water gets inside the instrument to prevent possible short circuits
and damage.
