Introduction
The Model UT300A and UT300B Infrared Thermometer (hereafter, the “Thermometer”) can determine the surface temperature by measuring the amount of infrared energy
radiated by the target’s surface. They have different distance to spot (D:S) figure and different temperature range, details see the contents.
The Thermometers are non-contact infrared thermometer with low consumption design so that they can be used for a longer time, which can solve the frequently changing
battery and low battery issues during measurement. Intelligent design can make measurement easier and quicker. The Thermometer can intelligently select battery or USB
power source.

Safety Information
Warning
Awarning identifies conditions and actions that pose hazards to the user. To avoid electrical shock or personal injury, follow these guidelines:
zDo not point laser directly at eye or indirectly off reflective surfaces.
zBefore using the Thermometer inspect the case. Do not use the Thermometer if it appears damaged. Look for cracks or missing plastic.
zReplace the battery as soon as the battery indicator appears.
zDo not use the Thermometer if it operates abnormally. Protection may be impaired. When in doubt, have the Thermometer serviced.
zDo not operate the Thermometer around explosive gas, vapor, or dust.
zTo avoid a burn hazard, remember that highly reflective objects will often result in lower than actual temperature measurements.
zDo not use in a manner not specified by this manual or the protection supplied by the equipment may be impaired.

How the Thermometer Works
Infrared thermometers measure the surface temperature of an opaque object. The Thermometer’s optics sense infrared energy, which is collected and focused onto a detector.
The Thermometer’s electronics then translate the information into a displayed temperature reading which appears on the display. The laser is used for aiming purposes only.
Operating the Thermometer
The Thermometer turns on when you press the trigger. The Thermometer turns off when no activity is detected for 8 seconds.
To measure temperature, aim the Thermometer at the target, pull and hold the trigger. Release the trigger to hold a temperature reading.
Be sure to consider distance-to-spot size ratio and filed of view. The laser is used for aiming only.
