4. Initial Setup
4.1 Charging the Battery
Before first use, fully charge the thermal imager's built-in rechargeable battery. Connect the provided Type-C data cable to the device and a suitable USB power adapter (not included). The charging indicator will show the charging status. A full charge typically takes less than 3 hours and provides approximately 7 hours of operating time.

4.2 Powering On/Off
- To Power On: Press and hold the power button (usually marked with a universal power symbol) until the screen illuminates.
- To Power Off: Press and hold the power button again until the device shuts down.
5. Operation
5.1 Basic Temperature Measurement
Point the thermal imager at the target object. The screen will display the thermal image along with temperature readings. The device automatically captures the center point, highest (Max), and lowest (Min) temperatures within the field of view.

5.2 TISR Image Enhancement
The TISR (Thermal Image Super Resolution) technology enhances the clarity and integrity of the thermal image, upscaling the resolution to 240x240 pixels for more precise analysis. This mode can typically be toggled on/off via the device's menu or a dedicated button.

5.3 Color Palettes
The device offers 6 adjustable color palettes to visualize temperature differences. You can switch between these palettes (e.g., White Hot, Black Hot, Rainbow, Iron Red, Red Hot, Merge) to best suit your inspection needs and enhance the identification of thermal patterns. Access these options through the device's menu.

5.4 Over-temperature Alarm
Set customizable alarm thresholds to receive real-time alerts when temperatures exceed or fall below a specified range. This feature is crucial for quick response in critical monitoring situations.

5.5 Flashlight Auxiliary
The built-in flashlight enhances operational capability in dark environments, providing visible light when needed for better context or navigation.

5.6 Language and Unit Switching
The device supports multiple display languages and temperature units (Celsius °C, Fahrenheit °F, Kelvin K). These settings can be adjusted in the system menu to suit user preferences and regional requirements.


5.7 Dual Light Fusion (YXI96 Pro)
The YXI96 Pro model features dual light fusion, combining thermal and visible light images to more accurately identify targets in complex environments.

6. Data Management
6.1 Photo and Video Recording
The thermal imager supports both photo and video recording. Use the dedicated buttons or menu options to capture thermal images or record video footage for later analysis.
6.2 SD Card Storage and PC Software
The device uses an external SD card for data storage. Captured images and videos can be transferred to a computer for detailed analysis using professional PC software. This software allows for point, line, and surface temperature analysis, and the instant generation and export of analysis reports.
