INTRODUCTION
Thank you for purchasing this infrared thermometer. By simply pressing a push button and owing
to infrared rays, it is possible to carry out temperature measurements without coming into contact
with the object. The built-in laser pointer increases measurement accuracy while the retroilluminated
LCD display and practical push-buttons combine for convenient and ergonomic use.
The Non-contact Infrared Thermometers can be used to measure the surface temperature of an
object which might be indicated with difculty via traditional contact thermometers (for example,
it is very easy for moving objects, surfaces under voltage or those objects which cannot be easily
touched.)
Proper use and care of this tool will guarantee years of durable and reliable service.
FEATURES:
Rapid detection function
Precise temperature measurement without need of contact
Dual laser pointing
Unique smooth surface, modern housing design
Measurement maintenance function (Data Hold)
℃/℉ selection push button
Digitally adjustable emissivity from 0.10 to 1.0
MAX temperature display
Retroilluminated LCD display
Automatic selection range and Display Resolution 0.1ºC (0.1ºF)

SAFETY
Use extreme caution when the pointer laser ray is turned on.
Do not point the laser ray towards people or animals because it is dan-
gerous for the eyes.
Be careful not to point the laser beam on a reective surfaces or mirrors
which could cause damage to sight .
Do not point the laser beam towards explosive substances or gases.

DISTANCE & DIMENSIONS OF THE LASER BEAM
Hand in hand with the increase of distance (D) between the thermometer and the object from which
the temperature measurement is desired, the diameter of the laser beam (S) or the area measured
becomes larger. The relationship between distance and dimensions of the laser beam is indicated
as follows for the different thermometer models. The focal point is 914mm (36”). The laser beam
dimensions correspond to 90% of energy emitted.

“Down” button (for Emissivity, high or low alarm: EMS,HAL,LAL)
MODE selection button (for passing from one function to another)
MEASURMENT OPERATION
Selection of the temperature measurement unit (°C or °F)
During the measurement operation, use the “up” and “down” keys to adjust the emissivity.
During the measurement maintenance function use the “up” key to activate or de-activate the
laser, or the “down” key to switch the retroillumination on or off.
To set up High (HAL) and Low Alarm ( LAL) values and Emissivity (EMS), press and hold
the selection MODE key until the appropriate symbol is not on the display, press the UP and
down buttons to adjust the desired values.

MODE Selection Key Function
Pressing this button also enables access to the Emissivity set up function
(EMS),activation/de-activation of the continuous measurement mode, of the
activation/de-activation and regulation of the high (HAL) and low (LAL)
alarm. Each time you press the selection MODE key, the instrument passes
to the subsequent function. The diagram shows the cycle sequence of the
various modes.
EMS adjustment.
The Emissivity(EMS) is digitally adjustable from 0.10 to 1.0.
Activation/De-activation mode for CONTINUOUS MEASUREMENT
The continuous measurement mode is particularly useful for the continuous
monitoring of temperature. Press the “up” and “down”keys to activate it/de-
activate it. Press the measurement push button (trigger) to conrm continuous
measurement mode. The instrument continues to display temperature even if
the trigger is not pressed again.
In the continuous measurement mode, press the up and down keys to adjust
emissivity or activate/de-activate the high (HAL) low (LAL) alarm. Press the
measurement button (trigger) to conrm the High/Low alarm method.

°C or °F Selection Push Button
Select the temperature measurement units (oC or oF) using the oC/oF selection
key ( )
The word “Max” indicates the maximum registration displayed each time in the
time elapsed from the moment when the activation/de-activation “ON/OFF” key
is pressed to the moment when it is released
MEASUREMENT OPERATION
Hold the thermometer and point it towards the surface where temperature measurement is
intended.
Pull and hold down the Trigger and proceed with the measurement operations. If the state of the
battery is good, the display lights up. Replace the battery if the display does not light.
Once the trigger has been released, the phrase HOLD appears on the display, to indicate that the
last reading has been memorized. In MAINTENANCE mode, press the UPbutton to activate or
de-activate the the laser. Press the DOWN button to turn on or off the retroillumination.
The instrument will automatically power down after approximately 7 seconds after the trigger is
released. (Unless the continuous measurement mode has not been activated)

BATTERY REPLACEMENT
When the battery discharge “ ” symbol appears on the thermometer display, it is necessary
to replace it with a new 9V battery.
Open battery carrier cover, then take out the battery from instrument and replace with a new
9-Volt battery. Finally close the battery carrier cover again.
NOTES:
How it Works. Infrared thermometers measure the surface temperature of an object. The op-
tical devices of the instrument indicate the energy emitted, reected, and transmitted that has
been gathered and converged on the sensor. The electronic circuits transform the signals into
temperature reading values which are then displayed on the instrument. The laser, when present,
serves only for the pointing phase.

Note: Measurement operations considerations
To correctly carry out measurement, grip the thermometer and point the infrared sensor towards
the object whose temperature is intended to be measured. The instrument is automatically capable
of compensating for temperature deviations owed to ambient temperature. Keep in mind that the
infrared sensor needs a certain time to stabilize in temperature. Therefore, if it is necessary to
carry out measurements on areas where there is a heightened thermal amplitude, it is necessary
to wait for a few moments before beginning measurement.

Visual Field. Make sure that the area where the temperature is to be measured is larger than
the diameter of the laser beam. The smaller such an area, the more necessary it is to be closer
to it. When accuracy is in doubt, make sure the area in question is at least twice as large as the
diameter of the laser beam.
Distance & Diameter of the LaserBeam. Gradually as the distance (D) increases between the
thermometer and the object whose temperature measurement is desired, the diameter of the laser
beam (S), or the area of measurement becomes larger. See: Fig: 1.
Looking for the hottest point.To look for the point of the object with the highest temperature,
carry outdifferentmeasurementsmoving thethermometerbeforetheoutside oftheareainvolved,
then on all of the surface of the object, with a movement from high to low.
Usage Limitations
The thermometer is not adapted to carry out measurements on reective or shining surfaces (
stainless steel, aluminum, etc.).See the paragraph relating to Emissivity
The instrument cannot measure through transparent surfaces such as glass: the value indicated
should indeed be that of the temperature of the glass.
Steam, dust, smoke, etc., can prevent accurate measurement by obstructing the temperature
reading.

Emissivity. Emissivity is a term used to describe the energy-emitting characteristics of different
materials. The emissivity of the great part of organic materials and painted or oxydised (90% of
standard applications) is equal to 0.95 (pre-set on the instrument). To compensate for possible
imprecise readings, which can result from measurements carried out on metal or shining surfaces,
cover the area to be measured with adhesive tape or opaque black paint and wait until this new
material reaches the same temperature of the object that it is protecting,. At this point, carry out
the temperature measurement.
