Introduction
Open the battery compartment by pulling forward on the front handle. Insert the batteries noting the polarity. Pull the trigger, and the temperature reading of the surface being measured will be shown on the LCD display. Use the circle laser pattern to identify the target area being measured. On the side of the unit are slots to insert a type T thermocouple probe (sold separately) for contact measurements.
Infrared measurements are affected by many factors including emissivity, distance, ambient temperature, material of target being measured and many other factors. For tips on using infrared thermometers visit the Learning Center at

Congratulations on purchasing a ThermoWorks precision instrument, the IRT-2 Infrared thermometer. Each instrument is factory tested and a certificate of conformance is included to ensure that it was tested against NIST-Traceable standards. Please review this operation guide prior to use.
Current emissivity setting. (The default emissivity is 0.95.)
Press ‘Mode’ button, then press ‘Up’ key or ‘Down’ key to set the emissivity. Press ‘Mode’ key to save. The emissivity is settable from 0.10 (10E) to 1 (100E).
Press ‘Mode’ button to view Maximum (MAX), Minimum (MIN), Different between MAX and MIN (DIF) and Average (AVG) modes. All functions are reset when measurements resume.
Press ‘Up’ key or ‘Down’ key to change the High Alarm (HAL) or Lo Alarm (LAL), then press ‘Meas.’ key to save. Alarm will sound and screen will flash when limits are exceeded. Alarm is for infrared measurements only.
Connect a suitable type T thermocouple probe to the connection on the side of the unit. Within the PRB function the temperature of the probe will be displayed in the lower display.
Press the “Lock” button to enable the continuous operation mode. In this mode the unit will measure without requiring the press of the trigger. Press ‘Lock’ button again to disable continuous operation mode.

Troubleshooting
The thermometer should be stored at room temperature. The sensor lens is the most delicate part of the thermometer. The lens should be kept clean at all times; care should be taken when cleaning the lens using only a soft cloth or cotton swab with water or medical alcohol, allowing the lens to fully dry before using the thermometer. Do not submerge any part of the thermometer.
When the ‘Low Battery’ icon flashes, the battery should be replaced immediately with AAA, 1.5V batteries. Please
note: Turn the instrument off before replacing the battery.
Dispose of used battery promptly and keep away from children.

EMC/RFI: Readings may affected if the unit is operated within the radio frequency electromagnetic field strength of
approximately 3 volts per meter, but the performance of the instrument will not be permanently affected.
*IR accuracy can be affected by the emissivity setting, target spot size and rapid changes in ambient temperature.
The thermometer incorporates visual diagnostic messages as follows:
‘Hi’ or ‘Lo’ is displayed when the temperature being measured is outside of the settings of HAL and LAL.
Er2’ is displayed when the thermometer is exposed to rapid changes in the ambient (working / room) temperature. ‘Er3’ is displayed when the ambient temperature exceeds 32°F (0°C) or 122°F (50°C). The thermometer should always be allowed plenty of time (minimum of 30 minutes) to stabilize to the ambient temperature.
Error 5-9 is displayed for all other error messages; it is necessary to reset the thermometer. To reset the thermometer, turn it off, remove the battery and wait for a minimum of one minute, reinsert the battery and turn on. If the error message remains, please contact Technical Support at techsupport@thermoworks.com for fur ther assistance. ‘Hi’ or ‘Lo’ is displayed when the temperature being measured is outside of the measurement range.
Battery Low’ Replace batteries. Measurements are not affected
Replace batteries
To turn on the LCD backlight, press the “Lock” button while holding down the trigger. Press again to turn the backlight off.
To turn on the circle laser, press the “C/F” button while holding down the trigger. Press again to turn the laser off.
