LASER SAFETY
Laser light can cause eye injury, if the
beam makes direct eye contact.
Reflected Laser light can also cause
damage, if a mirror or a glass-like
surface reflects the beam directly into
the eyes.
Laser's potential to cause damage is
retained for hundreds of feet.
To activate Laser sighting , press and
hold the trigger ,then press Laser key
, now laser beam shows on the surface
you want to measure .
Now , you see a laser icon is displayed
on the screen.
Do not point the laser toward the
eyes or face of a person or animal.

OPERATING INSTRUCTIONS
This instrument's light weight, pistol
grip design, flip battery compartment
and large LCD display make it
convenient for most temperature
measurement needs and accessible
to processes not suited for conventional
"contact" temperature measurements.
While releasing the trigger , the reading
will be freezed , icon indicates
holding the current measurement .
The meter will be automatically turn off
for saving power in 10 seconds under
non-operation .

TAKING MEASUREMENT SAMPLES
To take temperature measurements,
point the instrument at the surface to
be measured and pull the trigger.
A tube has been incorporated along the
top of the barrel to aid the user in
spotting the surface area to be
measured (target).
Although this simple explanation works
well in most cases, there are other
factors that may impact the
measurement accuracy.
Consider these influences before using
the data you obtain with your infrared
thermometer:
The target must completely fill the
spot diameter seen by the infrared
sensor, otherwise the temperature
displayed will be influenced by the
surface surrounding the target.
The ratio of the distance from the
end of the barrel to the size of the
spot being measured is 12 : 1.

When using the gun to find hot -spots,
accuracy of the reading is not as
important as keeping the gun at the
same distance from the target for
each sample measurement.
If you are looking for hot-spots on
electrical panels, for instance, you
could take the readings from 6' away
each time, even though you may
only be filling half the spot diameter.
The critical information in this process
would be any significantly higher
temperature .
Emissivity of an object will also
affect accuracy.
This instrument is sensitive to
electromagnetic interference (EMI),
such as that generated by spark
plug wires, radio transmitters and
welders. Do not use this instrument
in close proximity to equipment that
may produce such interference
The instrument must be used within
the ambient temperature range
specified in the specification table
For example, using the meter,an object
that is 6" in diameter can be accurately
measured from 72" away.

o
Select the scale you prefer to use ( F
ooo
or C) by pressing the ( " C/ F " )
push-button while the trigger is pulled.
BACKLIGHT OPERATION
To toggle the backlight on or off, press
the push-button with the backlight
( ) symbol while the trigger is pulled.
Once the backlight has been turned on,
it will come on each time the trigger is
pulled until it is toggled off.
Please note that this feature
significantly reduces the battery's life.
REAL-TIME TEMPERATURE
MEASUREMENT MODE
This display mode shows the actual
temperature of surfaces measured.
This value is updated at least once
every 1/2 second. When the instrument
is powered up for the first time, this
mode is pre-set.

EMISSIVITY ADJUSTMENT
When a process calls for repeated
measurements of like materials, such
as evaluating a plastic solidity at a
processing plant, the best method of
attaining quick, reliable temperature
readings is to adjust the emissivity
setting of your meter.
Press and hold the trigger , then press
MODE button , flash displays on the
screen . Please refer to the emissivity
table on pages 12,13 and 14 ,emissivity
value is adjustable from 0.30 to 1.0.
To decrease the value by pressing the
oo
( F/ C/ ) push-button. To increase
this value, press the ( / ) push-
button.
To save the newly set value, press the
MODE/SAVE push-button again, now
LCD turns to the normal mode icon
now stop flashing.

TROUBLESHOOTING
No display or erratic display:
Check the battery for proper voltage
and tight contact at the battery clip.
Ensure the unit is at the specified
operating temperature.
Constant or spurious over-load
(OL) display:
Check battery voltage. Check
for electromagnetic interference
(EMI).
To check for EMI, move the unit to an
open area, away from high voltage
and radio or radar transmitting
sources.
Erroneous temperature readings:
Inspect the infrared lens for blockage
or contamination.

11
MAINTENANCE
Follow cleaning instructions. Check
battery for proper voltage and tight fit in
the battery clip.
Ensure the small red and black wires
are not in a position to be pinched or
cut, as the battery is replaced in its slot.
Case cleaning :
Use caution with a damp cloth to clean
the exterior housing , ensure no water
or soap is allowed inside the meter ,or
on the infrared lens.
Lens cleaning :
WARNING : Recommend to clean the
lens after a time of period using the
meter and make sure the lens is clean
enough to ensure the reading accuracy.
By using low pressure compressed air
to remove any particles on the lens ,
if the contamination can not be
removed with air , use a soft cotton
swab .
