Ⅰ. Safety information
Please read the following information carefully
before using the meter.
Do not clear the meter using solvents.
Safety symbols:
Important information prompt for denger.
Comply with European CE safety standards.
This instrument is compatible with the following standards:
EN61326-1

Warning
Do not point laser directly at eye or indirectly off
reflective surfaces.
Ⅱ. Cautions
When ambient temperature changes quickly, must wait
30 minutes to balance the the heat of the instrument
before use.
Avoid EMF(electro magnetic fields) from arc weld,
induction furnace, ect…
Do not leave the unit on or near high temperature
objects.
Keep the instrument clean, and do not get dust into
detecting hole.

Ⅴ. Measurement principle
Noncontact Themometer detects the infrared ray that
an object emits, The instrument foculizes infrared energy
of the object onto a sensor through a lens, changes the
surface temperature into electric signal, a microcomputer
calculates and displays the measurement temperature on
the LCD. The method can measure object’s surface
temperature without contact. The laser is used to aim
target only.
Ⅵ. Measurement method
1. To measure the temperature of an object, point the unit
at it, press the trigger down and keep, you can measure
the temperature continuously. After releaseing trigger,
LCD will hold the result of measurement. The first
temperature indicates the current measurement value;
the second temperature indicates the calculated value.
To get an accurate measurement result, refer to D:S
ratio,Emissivity sections. The instrument will turn off
after releasing trigger for 10 seconds.
2. When an object is far from the thermometer, by pressing
3
laser button to light the laser to aim at object.
3. To measure in the night, by pressing backlight button to
light the backlight.
4. By pressing “MODE” button to change the mode of the
second temperature, it can show AVG(average)
MAX(maximum), MIN(minimum), MAX-MIN.
5. By pressing ℃/℉ button to choose ℃ or ℉
temperature unit to show temperature.
Ⅶ. D:S ratio
The thermometer has a visual angle and visual spot size, a
drawing shows it as following:
Object
focus tube sensor
Make sure that the target is larger than the unit’s visual spot
size. The smaller the target, the closer you should be to it.
The relationship between distance and spot size is 12:1, the
drawing as following:

To prevent the infrared of other object from entering
thermometer, you had better be closer to object than the
distance calculated by ratio D:S=12:1.
Ⅷ. Emissivity
Emissivity is used to describe the energy emitting
characteristic of materials. The greater the emissivity, the
stronger the emission capacity of the object is. Most
organic materials and oxidized metal surfaces have a
emissivity between 0.85 to 0.98. The thermometer is
designed according to that emissivity equals 0.95. When
the Emissivity of an object is less than 0.95, the
measurement temperature is less than the actual
temperature; and the emissivity of an object is more than
0.95, the measurement temperature is more than the fact
temperature. A shiny metal or a polished object surface has
a low emissivity. Please pay attention to the effect of
emissivity of objects.
Ⅸ. Changing the battery
When the battery voltage is lower,
the battery symbol appears, it
indicates that we must change the
battery. Pinch OPEN characters on
the battery cover, then pull it and
can change a new battery. See the
drawing as right:
