•
Read the manual carefully before using the
device!
•
Do not clean the device with solvents.
•
Safety symbols:
Warning sign
Complies to European CE safety
standards
•
The device complies to the following
standards:
EN61326-1, EN61010-1, EN60825-1
WARNING!
Do not direct the laser straight in the eye
or to any relecting surface!
•
When used in areas with diferent
temperatures allow 30 minutes for the device
to adapt to the proper temperature before
measuring.
•
Keep the device away from electromagnetic
ields, welding, induction forges, etc.
•
Do not leave the device on a high temperature
object or close to it.
•
Keep the device clean to prevent dirt in the
laser and other gaps.

easUring
principle
The device senses the infrared beams radiated
from an object. The device focuses the infrared
energy of an object through a lentil into a
sensor, then converts the surface temperature
into electronic signals and a microcomputer
calculates and displays the measured value on
an LCD screen. The device measures the surface
temperature of an object without direct touch.
Only point the laser onto the measured object.

MetHod
•
To measure the temperature of an object
point the device on it and press the trigger.
Continous measuring is possible with
holding down the trigger. The LCD shows
the measured value even after the trigger is
released. For an accurate result consider the
D:S ratio and emissivity. The device turns of 15
seconds after the last measurement.
•
If the object is far away from the device the
laser beam can be turned on with the laser
button to help aiming.
•
Select °C or °F as units by pressing the °C/°F
button.
d:s
ratio
The device has a vision angle and a spot size, as
described on the below igure:
Object
Focus pipe Sensor
Make sure that the object is larger than the
spot size of the unit. To reduce this you need to
move closer to the object. The ratio between
the distance and the spot is 6:1, as shown on the
below igure:

D : S = 6 : 1
Spot (S) Distance(D)
To avoid interference with another object's
infrared light move closer to the object until the
D:S ratio equals 6:1
e
Missivity
Emissivity describes the energy emission
characteristics of materials. Enhancing
emissivity means enlarging the emission
capabilities of an object. Organic materials
and oxidized metal surfaces have emissivity
between 0.85-0.98. The device was designed
for emissivity that equals 0.95. If the emissivity
of the object is lower than 0.95m the
measured temperature is lower than the actual
temperature and vica versa.
A shiny metal surface or a smooth painted
surface has low emissivity. Pay attention to the
efects of emissivity!
Battery replacement
If the battery power signal indicates a depleted
battery you need to replace the battery to
ensure accurate measurement as described
below:
•
Pull of the battery holder cover
•
Remove the cover
•
Replace the battery
