EMISSIVITY
Emissivity (EMS) adjustment:
When first scrolling through MODE the will flash and
the Up / Down buttons can be used to change the
Emissivity value. Press the measurement trigger to
confirm selected emissivity, or continue through the
MODE menu cycle for other options.
Alternatively, adjust the Emissivity during measure-
ment: while holding the measurement trigger, using the
Up / Down buttons. The Emissivity is adjustable
from 0.10 to 1.0.
The selected emissivity value will remain after turning
off and until another value is selected.
Note on Emissivity:
Emissivity is a term used to describe the energy-emit-
ting characteristics of materials. Most (90% of typical
applications) organic materials and painted or oxidized
surfaces have an emissivity of 0.95 (pre-set in the unit).
Inaccurate readings will result from measuring shiny
or polished metal surfaces. To compensate, cover the
surface to be measured with masking tape or flat black
paint. Allow time for the tape to reach the same tem-
perature as the material underneath it. Measure the
temperature of the tape or painted surface.

LOCK ON/OFF
The lock mode is useful for continuous monitoring of
temperatures. Scroll through MODE until the icon
flashes and press the Up or Down buttons to turn on or
off the LOCK mode. Press the measurement trigger to
confirm the lock measurement mode.
‘LOCK on’ allows for continuous measurement reading,
beyond the 8-second automatic time-off.
Continuous measurements are taken without the trig-
ger being pressed. Pressing the trigger will cancel the
HOLD command. [The IR Thermometer will continuously
display the temperature until the measurement trigger
is pressed again.]
“Lock off’ means the IRT2 will automatically turn off
after 8 seconds on non-use.
Emissivity can be adjusted while in ‘LOCK on’ mode by
pressing the Up or Down button.
ALARM – HIGH & LOW TEMPERATURE
The High / Low Alarm settings allow for the audio and
visual alarm turned on or off and for the high and low
temperatures to be adjusted according to your needs.
The audio alarm is a continuous beep. The visual alarm
is a flashing red backlight and flashing icon for a
high reading, or icon for a low reading.

HAL ON/OFF (High Alarm)
Scroll through MODE until the icon flashes with
ON or OFF showing on the screen. Press either the
Up or Down button to turn HAL ON or OFF. Press the
Measurement Trigger to confirm the High alarm on or
off mode, or continue scrolling through Mode for high
temperature adjustment and for other options.
HAL Adjustment (High Alarm)
Scroll through MODE until the icon flashes
with previous High temperature alarm setting value
showing on the screen. Press the Up or Down button to
adjust the High temperature alarm setting. Press the
Measurement Trigger to confirm the High temperature
alarm setting.
The High / Low alarm is adjustable form -50ºC to +650
ºC (-58ºF to +1202ºF) Adjustments can be made in
increments of 0.1. If the Up / Down buttons are
continually pressed, adjustments will be made in
increments of 1, 10 and 100.

Scroll through MODE until the icon flashes with
previous Low temperature alarm setting value showing
on the screen. Press the Up or Down button to adjust
the Low temperature alarm setting. Press the Measure-
ment Trigger to confirm the Low temperature.
The High / Low alarm is adjustable form -50ºC to +650
ºC (-58ºF to +1202ºF)

MEASUREMENT OPERATION
1) Hold the meter by its Handle Grip and point it toward
the surface to be measured.
2) Pull and hold the measurement trigger to turn the
meter on and begin testing. The display will light if the
battery is good. Replace the battery if the display does
not light.
3) Release the measurement trigger and the HOLD
display icon will appear on the LCD indicating that the
reading is being held. In HOLD status, press the UP
button to turn on or off the laser. And press the DOWN
button to turn on or off the backlight.
4) The meter will automatically power down after ap-
proximately 7 seconds after the measurement trigger is
released, unless the unit is set to LOCK mode.

NOTES on Operation
Measurement and ambient temperature:
Holding the meter by its handle, point the IR Sensor to-
ward the object whose temperature is to be measured.
The meter automatically compensates for temperature
deviations from ambient temperature. Keep in mind
that it will take up to 30 minutes to adjust to wide
ambient temperatures are to be measured followed by
high temperature measurements, some time (several
minutes) is required after the low (and before the high)
temperature measurements are made.
This is a result of the cooling process, which must take
place for the IR sensor.
How it Works
Infrared thermometers measure the surface tem-
perature of an object. The unit’s optics sense emitted,
reflected, and transmitted energy, which is collected
and focused onto a detector. The unit’s electronics
translate the information into a temperature reading,
which is displayed on the unit. In units with a laser, the
laser is used for aiming purposes only.
Field of View
Make sure that the target is larger than the unit’s spot
size.The smaller the target, the closer you should be to it.
When accuracy is critical, make sure the target is at least
twice as large as the spot size.

Distance & Spot Size
As the distance (D) from the object increases, the spot
size (S) of the area measured by the unit becomes
larger.
The relationship between distance and spot size for
each unit is listed below (in SPECIFICATIONS). The
focal point for each unit is 914mm (36”). The spot sizes
indicate 90% encircled energy. The focal point for
each unit is 914mm (36”). The spot sizes indicate 90%
encircled energy.
Locating a hot spot
To find a hot spot aim the thermometer outside the area
of interest, then scan across with an up and down motion
until you locate hot spot.

Reminders
1) Not recommended for use in measuring shiny or
polished metal surfaces (stainless steel, aluminum, etc.).
See Emissivity
2) The unit cannot measure through transparent surfaces
such as glass. It will measure the surface temperature of
the glass instead.
3) Steam, dust, smoke, etc., can prevent accurate
measurement by obstructing the unit’s optics.
BATTERY REPLACEMENT
1) As battery power is not sufficient, LCD will display
replacement with one new battery type 9V is required.
2) Open battery cover, take the battery out of the
instrument and replace with a new 9-Volt battery, then
replace the battery cover.

MAINTENANCE
Clean the lens often, but never use a solvent. Abrupt
temperature changes will cause condensation and
possible vapor penetration.
Clean after the vapor evaporates. Blow off loose parti-
cles with clean, compressed air. Gently brush remaining
debris away with a lens hair brush.
Carefully wipe the surface with a moist cotton swab.
Avoid water, moisture and corrosive gas or liquids. The
housing can be cleaned with a damp sponge. Remove
the battery when storing this product for an extended
period of time.
Do not drop or disassemble the instrument or immerse
it in water.
Repairs or service are not covered in this manual and
should only be carried out by qualified trained techni-
cian.
For service, use only manufacturer’s specified parts.

SAFETY INSTRUCTIONS
• Keep this instrument out of the reach of children.
• Do not point laser near or into eyes.
• Do not stare at the laser beam through binoculars or
a magnifying glass!
• Do not operate this instrument in the presence of
flammable/explosive gases!
• Do not operate in environments full of dust or static
electricity.
• Do not operate near sources of strong electromag-
netic fields, such as arc welders or induction heaters.
Finally, be aware that it is an offence to point a laser
beam at aircraft.
