Warning!
Do not point laser directly or indirectly (through reflective surfaces)
at eye.
2. Operation
1) Turn on
Install the battery and press the measurement button, then the
thermometer will be turned on and show the temperature reading
automatically.
2) LCD display
The LCD will display the signal of functions (as in diagram 3)
3) Measurement
Aim at target with thermometer head, and press the measurement
trigger, then release the button (need to press the button for at least
0.5 second), the display will show the current temperature, or press
and hold the button for continuous testing with more temperature
results
4) Turn off
The thermometer will turn off automatically after 15 seconds of no
operation

3. Distance Spot Ratio
The farther the target, the larger the testing spot area, it means: As
the distance from thermometer to the object increases, the spot size
of measuring area becomes larger, (as in diagram 1) it is named as
“D:S” (Distance Spot Ratio). The diameter of the target spot area is
3.0cm when you test from distance 36cm, and the thermometers will
show the average temperature of target spot area with diameter
3.0cm.
4. Emissivity
Most organic materials, painted or oxidized surfaces have an
emissivity of 0.95 (pre-set in the unit). Inaccurate readings will occur
if the surface to be measured is shiny or polished such as stainless
steel or aluminum. To obtain better accuracy, please cover the
surface with masking tape or flat black paint before measuring.
Measure the tape or painted surface when the tape or painted reach
the same temperature of the material underneath. Please kindly
note: thermometer can not measure the temperature of target
objects through the surface of glass. And steam, dust, smog will
lower the accuracy.

8.Emissivity: adjustable from 0.1 to 1.0 for testing of different articles
9.
Setting Display: display the related information you set
6. Infrared thermometer should be protected in the following:
--EMF (electro-magnetic fields) from arc welders, induction
heaters.
--Thermal shock (caused by large or abrupt ambient temperature
changes, it allows 30 minutes for unit to stabilize before use).
--Do not leave the unit on or near objects of high temperature.
7. Maintenance
1. Lens cleaning: use clean compressed air to blow off loose
particles, use a soft brush to remove debris, at last clean it with
damp cotton cloth.
2. Case cleaning: clean the case with a damp sponge/cloth and
mild soap.
NOTE:
1. Do not use solvent to clean lens.
2. Do not submerge the unit in water
