Operating Instructions
Taking Measurements
To take a temperature measurement using your INF165, you simply point the
aperture at an object and pull the trigger. The object’s temperature will show
up on the display and update at a rate of approximately 2 times per second.
There will be a delay of approximately one second between the time you
initially pull the trigger and the time the display comes on. The 60-second
auto-hold initiates at the moment you release the trigger. The maximum
temperature is viewed beside the “ “ icon.
NOTE : This thermometer will automatically shut off if left idle for more than 15 seconds.
Follow these general guidelines to ensure you get the most accurate readings possible
- Be sure the measured object fills the “spot” seen by the aperture. The distance-to-spot ratio for the INF165 is 12:1.
This shows the one-foot spot fitting within the one-foot target area. At this distance, and anything closer, the target’s temperature will be accurately measured. NOTE: If the two-foot diameter spot includes unwanted objects in the background that are not part of the one-foot target, the temperature of the background objects will be figured in with the target’s temperature and cause errors in your measurements.
Safety Notes
Before using this meter, read all safety information carefully.
In this manual the word “WARNING” is used to indicate conditions or actions
that may pose physical hazards to the user. The word “CAUTION” is used to
indicate con-ditions or actions that may damage this instrument.
NOTE: The INF165 is not recommended for use on shiny surfaces such as chrome,
mirrors or polished metals.
WARNING!
To avoid thermal shock, the instrument should be stored at room temperature
between 32˚ to 122˚F (0˚ to +50˚C).
WARNING!
DO NOT look directly into the laser beam. Permanent eye damage may result.
CAUTION LASER RADIATION – DO NOT STARE INTO BEAM CLASS II LASER PRODUCT Max Output<1mV – Wavelength 635-660nm

- Battery Level
- When comparing temperatures of similar objects that are far away, take your measurements at the same distance and angle to the target each time.
- When looking for abnormally hot or cold targets it may be acceptable to include background objects so long as the temperatures in the background and your methods are consistent.
- Consider the emissivity of the objects you are measuring.
- Prepare a surface for measurement. Infrared thermometers measure only the outer surface of an object. If emissivity is affecting the measurement, or you have difficulty putting the object in the sensors line-of-site, you may need to prepare a surface that’s easy for the infrared thermometer to read. A piece of masking tape is a good target and it will rapidly take on the temperature of the object it is attached to.
- Be aware that you cannot measure the temperature of air between the Infrared thermometer and an object. Air vents (registers) are quick to take on the temperature of outlet air. However, you must aim directly at the vent if you are measuring outlet air temperature.
- Keep your infrared thermometer away from strong electrical fields. When working near a strong electrical field, like that under the hood of your car, watch for unusual readings or an “over load” indication. Often, you can move the thermometer just a few inches to escape the influence of the interference.
- Keep your INF165 within its use and storage temperature range. Excessive heat or cold will adversely affect the accuracy of your readings. When the trigger is pulled the target’s temperature will be displayed in a near real-time mode (less than 1/2 second between measurements). The temperature will remain on the display for sixty seconds after the trigger is released.
Emissivity
-
Not all surfaces emit infrared energy at the same level. A shiny surface will emit much less infrared energy at a given temperature when compared to a flat black surface. The INF165 has two preset emissivity levels used to compensate for variances in your target.
High (0.95) will work for most common surfaces and is set as default for many infrared thermometers. Medium (070) is best for oxidized copper or rusty iron. -

Changing Scales
To change scales between degrees Fahrenheit and degrees Celsius, press the
button on the panel, (marked °C / °F), while the display is active. Even if
the trigger is released and the display is in its 60-second automatic hold,
you can convert the reading between scales. Each time you press the scale
button, the 60-second hold will reset. The INF165 will default to the scale
last used the next time it is turned on.
Using the Laser Sight
The INF165 is classified as a “Laser Product”, and is regulated by the FDA.
The laser and backlight are always on when the trigger is pulled.
CAUTION!
Using controls, making adjustments, or performing procedures in any manner
other than that specified herein may result in hazardous laser radiation
exposure.
LCD Error Messages
The thermometer incorporates visual diagnostic messages as follows:
To reset the thermometer, turn the instrument off, remove the battery and wait for a minimum of one minute. Reinsert the battery and turn it on. If the error message remains please contact UEi service department for further assistance.
Battery Indicators
The thermometer incorporates visual low battery indications.
Lens Care
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 in liquids.
WARNING!
Under NO circumstance should you expose batteries to extreme heat or fire as
they may explode and cause injury.
NOTE: This instrument contains no user serviceable parts. If service becomes
necessary, call UEi and ask for the service department. See the warranty
section of this manual for additional details.
