Laser Radiation, Do Not stare Into
Beam, Class 2 Laser Product

Laser Radiation
• Do not stare into beam.
Class 2 laser product. Turn the laser beam on only
when using this tool.
1. Do not remove or deface the product labels.
2. Avoid direct eye exposure. The laser beam can
cause ash blindness.
3. Do not operate the tool around children or allow
children to operate the tool.
4. Do not place the tool in a position that may
cause anyone to stare at the laser beam, whether
intentionally or unintentionally.
5. Do not use on surfaces such as sheet steel that
have shiny, reective surfaces. The shiny surface
could reect the beam back at the operator.
6. Always turn the laser tool off when not in use.
Leaving the tool on increases the risk of someone
inadvertently staring into the laser beam.
7. Do not attempt to modify the performance of this
laser device in any way. This may result in a
dangerous exposure to the laser radiation.
8. Do not attempt to repair or disassemble the laser
measuring tool. If an unqualied person attempts
to repair this product, serious injury may occur.
Any repair required on this laser product should
be performed only by qualied service personnel.

Maintenance
Maintenance Information
• Use a dry, clean cloth to clean the instrument.
• Do not use solvents.
• For extra protection, always store the instrument
in the case provided when not in use.
• If there is a sudden change in the environmental
temperature, the instrument should be acclimatised
for a minimum of 30 minutes. This will ensure the
ambient temperature is the same, both inside and
outside of the thermometer.
• The electromagnetic eld from electric welding and
inductive heating must be minimized.
• Do not place the thermometer near to hot objects.
• The meter must be kept clean so that dust is denied
access to the lens cone.

Measurement Operation
Setting the high alarm.
• Pull trigger and press mode key once for two
seconds, then release trigger. This will show HI.
Use the left and right buttons / to set the
required alarm level.
• Once high values are set, press the mode button
one more time & this will show LOW.
Use the left & right buttons / to set the
required low alarm level.
• When alarm levels are reached RED LED light
will illuminate.
Setting the emissivity
• To set the emissivity, pull the trigger and press
mode for two seconds. scroll through by pressing
mode until the display shows E.
The emissivity can now be set (see values on
page 12/13.
Use the left & right buttons / to set the
required emissivity level.
Setting the Celsius & Fahrenheit
• To set the temperature unit, pull the trigger and
press mode for two seconds. scroll through by
pressing mode until the display shows °C.

Measurement Operation
Use the left & right buttons / to set the
required temperature unit required °C/ °F .
Enabling the Laser
• Enable / disable laser. Press key to enable or
disable laser. The instrument will display the
symbol for laser
Non-contact temperature measurement
• Target the IR thermometer at an object and pull
the trigger. Hold the trigger to take continuous
measurement of temperature.

Distance To Spot Ratio (D:S)
10
Distance To Spot Ratio (D:S)
Proportion between the distance from the
instrument to an object and the diameter of
the object to be measured (D:S)
The IR Thermometer has a certain angle and
eld of vision, as shown in the diagram below:
It must be ensured that the object to be measured
is fully within the eld of vision afforded by the
IR Thermometer, that is, the laser ring can see
nothing but the object to be measured. The greater
the object to be measured, the further the distance
between the object & thermometer must be. The
smaller the object is, the shorter the distance
between the object & thermometer must be. The
proportion between the distance to be measured and
the size of the object to be measured (D:S) is 12:1, as
shown on page 10.

be measured Lens Photosensitive element

Distance To Spot Ratio (D:S)
While measuring an object, the instrument will emit
an indicative ring. The measured temperature of the
surface is the internal temperature of the ring.

Emissivity

Emissivity Reference Table
Emissivity
Emissivity refers to the ability of an object
to emit infrared ray. The greater the emissivity
is, the stronger the emission ability of the
surface of an object is.
The emissivity of most organic substances or
oxidized surfaces of metals falls within the range
of 0.85 ~ 0.98. The default emissivity of this
measurement device is 0.95.
The instrument’s emissivity is set to be consistent
with that of the object to be measured at the
moment of measurement result must be noticed at
the time of measurement.
