5.2 Menu Navigation
Use the navigation buttons (up, down, left, right, OK/SET) to access and navigate through the device's menu. The menu allows you to adjust settings such as:
- Palette: Change the color scheme of the thermal image (e.g., Iron, Rainbow, White Hot, Black Hot).
- Emissivity: Adjust for different material surfaces to ensure accurate temperature readings.
- Temperature Unit: Switch between Celsius (°C) and Fahrenheit (°F).
- High/Low Temperature Tracking: Enable or disable automatic tracking of the hottest and coldest spots.
- Alarm Settings: Configure buzzer/flashlight alarms for specific temperature thresholds.
5.3 Image Capture and Storage
To capture a thermal image, press the trigger or the designated capture button. The image will be saved to the inserted Micro SD card. You can review captured images through the gallery function in the menu.
6. Maintenance
6.1 Cleaning the Device
Wipe the device casing with a soft, damp cloth. Do not use abrasive cleaners or solvents. For the lens, use a specialized lens cleaning cloth and solution to avoid scratching. Ensure the device is powered off before cleaning.
6.2 Battery Care
To prolong battery life, avoid fully discharging the battery frequently. If storing the device for an extended period, charge the battery to approximately 50% and store it in a cool, dry place. Recharge every few months to prevent deep discharge.
6.3 Storage
Store the thermal imager in its original packaging or a protective case when not in use. Keep it away from extreme temperatures, high humidity, and direct sunlight.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery; device malfunction. | Charge the battery. If problem persists, contact support. |
| Image is blurry or unclear. | Dirty lens; incorrect focus (if applicable); object too close/far. | Clean the lens. Ensure object is within measurement range. |
| Temperature readings are inaccurate. | Incorrect emissivity setting; environmental factors. | Adjust emissivity for the target material. Ensure stable measurement conditions. |
| Cannot save images. | Micro SD card full or not inserted correctly; card error. | Check Micro SD card insertion. Delete old files or replace card. Format card if necessary. |
