2. Safety Information
Please read all safety warnings carefully before using the device. Failure to follow these instructions may result in injury or damage to the device.
- Laser Safety: Do not point the laser directly at eyes or indirectly off reflective surfaces. The laser is for aiming purposes only.
- Not for Human Temperature: These thermometers are designed for industrial and surface temperature measurement, not for medical use or measuring human body temperature.
Figure 2: Important Safety Warning - Not for Human Use
This image clearly illustrates that the infrared thermometer is not intended for measuring human body temperature, emphasizing the safety warning with a prominent "NOT FOR HUMANS" text and a prohibition symbol over the device pointed at a person.
- Handling: Do not immerse the unit in water. Do not expose to extreme temperatures or humidity.
- Battery Safety: Ensure correct battery polarity. Remove batteries if the device will not be used for an extended period.

4. Setup
4.1 Battery Installation
Your Wintact thermometer requires AAA batteries for operation. To install or replace batteries:
- Locate the battery compartment on the handle of the thermometer.
- Open the battery compartment cover.
- Insert the AAA batteries, ensuring correct polarity (+/-).
- Close the battery compartment cover securely.

This image highlights the long battery life features of the thermometers, including a battery indicator on the display and the auto power-off function, which activates after 20 seconds of inactivity to conserve power.
5. Operating Instructions
5.1 Taking a Measurement
- Point the thermometer at the target surface.
- Pull and hold the trigger. The laser pointer will activate (if enabled) to help aim.
- The temperature reading will appear on the display within half a second.
- Release the trigger to hold the reading on the display.
5.2 Changing Temperature Units (°F/°C)
Press the °C/°F button (usually located near the display) to switch between Celsius and Fahrenheit units.
5.3 Adjustable Emissivity
Emissivity is the ability of a material to emit energy. Different surfaces have different emissivities. For accurate readings, adjust the emissivity setting to match the material being measured.
- WT550: Emissivity adjustable from 0.1 to 1.0. Use the Up/Down buttons (often labeled SET or EMS) to change the value.
- WT530: Emissivity adjustable from 0.8 to 0.95.
5.4 Measurement Modes (WT550)
The WT550 model offers advanced measurement modes:
Figure 6: Four Modes of Measurement
This image demonstrates the four measurement modes available on the WT550 model: Difference (DIF), Maximum (MAX), Average (AVG), and Minimum (MIN) temperature readings, shown in the context of measuring a steak on a grill.
- MAX: Displays the maximum temperature recorded during a scan.
- MIN: Displays the minimum temperature recorded during a scan.
- DIF: Displays the difference between the maximum and minimum temperatures.
- AVG: Displays the average temperature recorded during a scan.
5.5 Temperature Alarms (WT550)
The WT550 allows setting high and low temperature alarms.
Figure 7: High and Low Temperature Alarms
This graphic illustrates the high temperature alarm (HAL) and low temperature alarm (LAL) features of the WT550, showing how the device alerts the user when measured temperatures exceed or fall below predefined thresholds, with examples of a hot pizza oven and a cold freezer.
Refer to the device's on-screen menu or specific buttons for setting these alarm thresholds.
6. Maintenance
6.1 Cleaning
- Clean the lens with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Wipe the body of the thermometer with a damp cloth.
6.2 Storage
Store the thermometer in a cool, dry place away from direct sunlight and extreme temperatures. Remove batteries if storing for extended periods.
