This infrared thermometer is used for measuring the tem-
perature of the object's surface, which is applicable for va-
rious hot, hazardous or hard-toreach objects without contact
safely and quickly.
This unit consist of Optics, Temperature Sensor Signal
amplifier, Processing circuit and LCD Display. The Optics
collected the infrared energy emitted by object and focus onto
the Sensor. Then the sensor translates the energy into an
electricity signal. This signal will be turned out to be digital
shown on the LCD after the signal amplifier and processing
circuit.
1. Warning:
To avoid the potential situation may cause harm or dam-
age to people, please pay attention to the following items:
1) . Do not point laser directly at eye or indirectly off reflec-
tive surfaces.
2) . The unit cannot measure through transparent surfaces
such as glass or plastic. It will measure the surface tem-
perature of these materials instead.
3) . Steam, dust, smoke, or other particles can prevent acc-
urate measurement by obstructing by the units optics.
2. Cautions:
Infrared thermometer shouldbe protected forthe
following:
1). EMF (electro-magneticfields) from arcwelders,
induction heaters.
2). Thermal shock(cause by largeor abrupt ambient
temperature changes allow 30 minutes for unit to
stabilize before use).
3). Do notleave the uniton or nearobjects of high
temperature.
Emissivity: Most organicmaterials and paintedor
oxidized surfaces havean emissivity of0.95(preset in
the unit). Inaccuratereadings will resultfrom measuring
shiny or polishedmetal surfaces. To compensate forthis,
adjust the unitsemissivity reading orcover the surfaceto
be measured withmasking tape orflat black paint.
Measure the tapeor painted surfacewhen the tapeor
painted reach thesame temperature asthe material
underneath.
1. When take measurement, pay attention to the Distance
to Spot Size. As the Distance (D) from the target surface
increases, the spot size (S) of the area measured by the
unit becomes larger.
The Distance to Spot size of the unit is 12:1.
This unit is equipped with a laser, which is used for aiming.
2. Field of view:
Make sure the target is larger than the unit's spot size.
The smaller the target the closer measure distance.
When accuracy is critical, make sure the target is at least
twice as large as the spot size.

1. Operating the unit
1). Open the battery door and insert a 9V battery properly.
2). Pull the trigger to turn on the unit;
3). Aim at the target surface and pull the trigger, then temp-
erature will be shown on the LCD.
This unit is equipped with a laser, which is only used for
aiming.
2. Locating a Hot Spot
To find a hot spot, aim the thermometer outside of interest,
then scan across with an up and down motion until you
locate the hot spot. (Figure 1)

1. Lens Cleaning:
Blow off loose particles using clean compressed
air. Gently brush remaining debris away with a
moist cotton swab. The swab may be moistened
with water.
2. Case cleaning: Clean the case with a damp spo-
nge/cloth and mild soap.
Note:
1) Do not use solvent to clean plastic lens.
2) Do not submerge the unit in water.
