2. Safety Information
WARNING: Failure to follow these safety instructions may result in injury or damage to the device.
- DO NOT USE ON HUMANS OR ANIMALS: This thermometer is an industrial-grade device designed for surface temperature measurement of objects. It is not intended for medical use and cannot provide accurate body temperature readings.
- LASER SAFETY: Do not point the laser directly at eyes or indirectly off reflective surfaces. The laser is for aiming purposes only.
- NON-CONTACT MEASUREMENT: The device measures surface temperature. The red laser dot indicates the approximate center of the measurement area, but the actual measured surface is approximately 2 cm below the laser point.
- AVOID MEASURING THROUGH SMOKE OR STEAM: Ensure the measurement is taken without interference from smoke or steam to obtain accurate results.
- Keep the device away from children.
- Do not immerse the unit in water.
- Do not expose the device to extreme temperatures or direct sunlight for extended periods.

- 1 x User Manual
Image: The complete package contents: the WT313A thermometer, its user manual, and two AAA batteries.
4.2 Battery Installation
- Locate the battery compartment cover on the handle of the thermometer.
- Slide or open the cover to access the battery compartment.
- Insert two AAA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
- Close the battery compartment cover securely.
The device is now ready for use. A low battery indicator will appear on the display when the batteries need replacement.
5. Operating Instructions
5.1 Basic Measurement
- Point the thermometer at the target surface.
- Press and hold the measurement trigger. The laser pointer will activate to assist with aiming.
- The display will show the surface temperature in real-time.
- Release the trigger to hold the last measured temperature on the display (Data Hold function).
For optimal accuracy, maintain a distance-to-spot ratio of 12:1. This means for every 12 units of distance from the object, the measurement spot diameter is 1 unit. The optimal measuring distance is approximately 36 cm (14.17 inches).

5.2 Switching Temperature Units (°C/°F)
Press the °C/°F button (often combined with the Up/Down key) to toggle between Celsius and Fahrenheit temperature units.
5.3 Mode Functions
Press the MODE button to cycle through various functions:
- SCAN: Continuous measurement while the trigger is held.
- HOLD: Displays the last measured temperature after releasing the trigger.
- MAX/MIN: Displays the maximum or minimum temperature recorded during a continuous scan. To use, hold the trigger and slowly scan the target area.
- AT (Ambient Temperature): Measures the surrounding air temperature.
- HI/LOW (High/Low Temperature Alarm): Allows setting high and low temperature thresholds. If the measured temperature exceeds these limits, an alarm will sound, and an indicator light will flash.
- EMS (Emissivity): Adjusts the emissivity value for different materials.
- CAL (Calibration): Allows for calibration adjustment within a range of +/- 5°C to ensure measurement accuracy.

5.4 Adjustable Emissivity
Emissivity is the ability of a material to emit thermal energy. Different materials have different emissivity values. The WT313A allows you to adjust emissivity from 0.10 to 1.00 for accurate measurements on various surfaces.
- Press the MODE button until "EMS" appears on the display.
- Use the Up/Down buttons to adjust the emissivity value.
- Refer to a standard emissivity table for common materials if precise adjustment is needed.
