IR-GUN-S
High Accuracy Infrared Thermometer – Operating Instructions
The IR-GUN-S is a non-contact infrared thermometer for measuring surface temperatures. Please
remember to keep away from children and don't use it for safety related applications.

display the surface
temperature. The
Distance:Spot ratio is 12:1. Please make sure the target area is within the field of view.
MAIN FUNCTION
Indicates emissivity. (The default emissivity is 0.95.) For more information on emissivity values of various
surfaces, visit www.thermoworks.com.

STORAGE & CLEANING
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
rubbing alcohol, allowing the lens to fully dry before using the thermometer. Do not submerge any part of the thermometer.
LCD ERROR MESSAGES
The thermometer incorporates visual diagnostic messages as follows:
BATTERIES
The thermometer incorporates visual low battery indication as follows:
'Battery OK': measurements
are possible
When the 'Low Battery' icon indicates the battery is low, the battery should be replaced immediately with 2 AAA, 1.5V batteries.
Please note: It is important to turn the instrument off before replacing the battery otherwise the thermometer may malfunction.

The thermometer will automatically shut off if left idle for more than 60 sec.
EMC/RFI: Readings may be affected if the unit is operated within 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.
CAUTION
1. WHEN DEVICE IS IN USE, DO NOT LOOK DIRECTLY INTO THE LASER BEAM–PERMANENT EYE DAMAGE MAY RESULT.
2. USE EXTREME CAUTION WHEN OPERATING THE LASER.
3. NEVER POINT THE DEVICE TOWARDS ANYONE'S EYES.
P-10-003-02-f
4. KEEP OUT OF REACH OF ALL CHILDREN.
You will hear a beeping sounds 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
temperature. 'Er3' is displayed when the ambient temperature exceeds 0
(122°F). The thermometer should be allowed plenty of time (minimum 30 minutes) to
stabilize to the working/room temperature.
Error 5~9, for all other error messages it is necessary to reset the thermometer. To reset,
turn the instrument off, remove the batteries and wait for a minimum of one minute, reinsert
the batteries and turn on. If the error message remains please contact ThermoWorks'
Technical Support for further assistance at techsupport@thermoworks.com.
