INTRODUCTION
The IRT2 is a handheld, dual laser, non-contact Infrared
Thermometer with 12:1 distance to spot ratio and audi-
ble and visible high/low set point alarms. It is used to
measure and display surface temperatures within the
range of -50°C to 650°C (-58ºF to 1202ºF) and has an
accuracyofapproximately1to 1.5%(see Specifications
for details).The IRT2 has a fast response time (0.15 sec)
and is powered with a 9V battery and complies with
Class II UK/EU laser safety standard EN60285.

SWITCHING ºC/ºF
Select the temperature units (ºC or ºF)
using the ºC/ºF switch (1)
ON / OFF
Press and release the measurement trigger to turn the
IRT2 on.
The IRT2 automatically turns off after 8 seconds of
non-use.
The ‘LOCK on’ function allows the IRT2 to remain on
beyond the automatic off-time of 8 seconds (see LOCK
ON/OFF below).

MODE SETTINGS MENU
Having pressed and released the measurement trigger,
the MODE button can be pressed to access the following
settings:
• Emissivity (EMS);
• LOCK on/off ;
• High Alarm (HAL) on/off;
• High Alarm temperature
adjustment;
• Low Alarm (LAL) on/off;

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.
