4. Setup
4.1 Charging the Device
Before first use, fully charge the device's built-in Li-ion battery. Connect the supplied USB Type-C cable to the device's USB-C port and to a standard USB power adapter (not included) or a computer's USB port. The charging indicator will show the charging status.
4.2 Powering On/Off
Press and hold the power button (usually located on the side or top) for approximately 3 seconds to turn the device on or off.
4.3 Language Selection
Upon initial startup or via the settings menu, you can select your preferred language. The device supports 11 languages including English, Chinese, German, Russian, French, Spanish, Portuguese, Korean, Japanese, Italian, and Polish.
5. Operating Instructions
5.1 Thermal Imaging Mode
The thermal imaging mode allows for non-contact temperature measurement and visualization of heat distribution.
- Activate Thermal Mode: From the main screen, select the thermal imaging function. Refer to the control diagram for specific button functions.
- Temperature Measurement: The device displays real-time temperature readings, including minimum, maximum, and center point temperatures.
- Color Palettes: Choose from 15 different color palettes to visualize thermal images. This can enhance contrast and highlight specific temperature ranges.

Figure 3: The 15 color palette options available in thermal imaging mode.
- Emissivity Adjustment: For accurate temperature readings, adjust the emissivity setting (default 0.95) to match the material being measured. This setting can typically be found in the thermal imaging menu.
- Automatic Temperature Capture: The device can automatically identify and display the highest, lowest, and center point temperatures within the field of view.

5.2 Multimeter Mode
The multimeter function provides precise electrical measurements.
- Activate Multimeter Mode: Switch to multimeter mode using the designated button.
- Connect Probes: Insert the multimeter probes into the appropriate input jacks (COM, VΩmA, 10A MAX) on the device.
- Select Measurement Function: Use the function selection buttons to choose between AC/DC voltage, resistance, capacitance, diode, continuity, frequency, or duty cycle measurements.
- Take Measurements: Apply the probes to the circuit or component to be measured. The 20000-count display will show the reading.
- Hold and Range: Use the 'HOLD' button to freeze the current reading on the display. The 'RANGE' button allows for manual range selection if auto-ranging is not desired.

Figure 8: Examples of thermal imaging applications.
Example: Floor Heating Detection Method
To detect issues in underfloor heating systems:
- Pressurize the various branches of the underfloor heating system.
- Inject hot water into the leaking branch of the underfloor heating system.
- Check the condition of the underfloor heating system after 20 minutes.
- Use the thermal imaging instrument with emissivity set at 0.9-0.95.
- Identify temperature anomalies or leaks along the route.
- After finding the leakage point, open the floor tile for repair.
