5. Setup
5.1 Battery Installation
The Wintact WT313C requires two AAA batteries for operation. These are included in the package.
- Locate the battery compartment on the handle of the thermometer.
- Open the battery compartment cover.
- Insert two AAA batteries, ensuring correct polarity (+ and -) as indicated inside the compartment.
- Close the battery compartment cover securely.
The device is now ready for use. If the low battery indicator appears on the display, replace the batteries promptly.
6. Operating Instructions
6.1 Basic Measurement
- Point the thermometer at the target surface.
- Press and hold the trigger. The laser pointer will activate (if enabled) to help aim.
- The display will show the real-time surface temperature.
- Release the trigger to hold the last measured reading on the display.

6.3 Emissivity Adjustment
Emissivity is the ability of a material to emit thermal energy. Different materials have different emissivities. For accurate measurements, adjust the emissivity setting to match the target material.
- Press the 'MODE' button until 'EMS' appears on the display.
- Use the 'Up' and 'Down' arrow buttons to adjust the emissivity value (0.10 to 1.00).
- Press 'MODE' again to confirm and exit.
Note: Most organic materials, painted surfaces, and water have an emissivity of 0.95. Polished metals have lower emissivities.

6.4 High/Low Temperature Alarm
Set high and low temperature thresholds to be alerted when measurements fall outside the desired range.
- Press the 'MODE' button until 'HI' (High Alarm) or 'LOW' (Low Alarm) appears.
- Use the 'Up' and 'Down' arrow buttons to set the desired temperature threshold.
- Press 'MODE' again to save and cycle to the next setting or exit.
When the measured temperature exceeds the 'HI' setting or falls below the 'LOW' setting, an alarm light will illuminate.

6.5 Calibration Function
The calibration function allows for minor adjustments to the temperature readings to ensure accuracy.
- Press the 'MODE' button until 'CAL' appears on the display.
- Use the 'Up' and 'Down' arrow buttons to adjust the calibration value within a range of ±5℃ (or ±9℉).
- Press 'MODE' again to save and exit.

6.6 Data Hold, Max/Min, and Ambient Temperature
- Data Hold: After releasing the trigger, the last measured temperature will remain on the display.
- Max/Min Readings: While holding the trigger, the thermometer continuously scans. Press the 'MODE' button to cycle through MAX (maximum), MIN (minimum) temperatures recorded during the scan.
- Ambient Temperature: Press the 'MODE' button until 'AT' appears to view the ambient air temperature.

7. Maintenance
7.1 Cleaning
To ensure accurate readings and prolong the life of your thermometer, keep it clean.
- Lens Cleaning: The sensor lens is the most delicate part. Clean it with a soft, clean cloth or cotton swab moistened with water or medical alcohol. Do not use harsh chemicals.
- Housing Cleaning: Wipe the device housing with a damp cloth. Do not immerse the thermometer in water.
7.2 Battery Replacement
When the low battery indicator appears on the display, replace both AAA batteries as described in the 'Setup' section (5.1 Battery Installation).
7.3 Storage
Store the thermometer in a cool, dry place away from direct sunlight and extreme temperatures when not in use for extended periods.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/Device won't turn on | Dead or incorrectly installed batteries | Replace batteries, ensuring correct polarity. |
| Inaccurate readings | Incorrect emissivity setting; Lens is dirty; Distance to spot ratio exceeded; Measurement through smoke/steam. | Adjust emissivity for the target material; Clean the lens; Ensure measurement is within 12:1 D:S ratio; Avoid measuring through smoke or steam. |
| Laser not working | Laser disabled; Low battery. | Check settings to ensure laser is enabled; Replace batteries. |
| Display shows 'HI' or 'LOW' | Temperature exceeds/falls below measurement range. | Ensure the target temperature is within the device's specified range (-58℉ to 1472℉). |
