6.2 Adjusting Emissivity
Emissivity is a crucial setting for accurate temperature measurement. Different materials have different emissivity values. Refer to the common emissivity table below or in the device's menu to adjust the setting.
- Press the Menu button (4) to access the settings.
- Navigate using the Up and Down buttons (5) to find the 'Emissivity' option.
- Adjust the value between 0.01 and 1.00 to match the material being measured.
- Press the Confirm button (4) to save changes.

6.3 Changing Temperature Units
The device supports Celsius (°C), Fahrenheit (°F), and Kelvin (K).
- Access the Menu settings.
- Navigate to 'Temperature Unit'.
- Select your desired unit using the Up and Down buttons (5) and confirm with button (4).

6.4 Using Color Palettes
The HX1/HX3 offers 15 pseudo color modes to enhance visualization of temperature differences.
- Access the Menu settings.
- Navigate to 'Color Palette' or 'Swatches'.
- Select a palette that best highlights the thermal patterns for your application.

6.5 Capturing and Storing Images
- To capture a thermal image, press the Photo/Trigger button (10).
- The image will be saved to the built-in 4GB TF card in BMP format.
6.6 Data Export
To analyze stored images on a computer:
- Connect the thermal imager to your computer using the USB Type-C cable.
- The device will appear as a removable storage device.
- You can then access and transfer the BMP image files for further analysis or reporting.

6.7 Over-Temperature Alarm
The device features an over-temperature alarm that triggers when a set temperature threshold is exceeded or falls below a minimum. This alarm provides visual (red screen, LED flashing) and audible (buzz) alerts.
- Access the Menu settings.
- Navigate to 'Temperature Alarm'.
- Set the desired high and low temperature thresholds.
- Enable or disable the alarm as needed.
