3.5 Connectivity (Mobile App / PC Software)
The UTi260E/UTi320E supports communication with mobile apps and PC software for advanced analysis and real-time display. Connect the device via Type-C USB for PC communication or use Wi-Fi for mobile app connectivity (check product specifications for specific model features).
3.6 Temperature Measurement Features
- High/Low Temperature Alarm: Alerts the user when temperatures exceed or fall below set thresholds.
- Automatic Tracking: Automatically tracks the hottest and coldest spots in the field of view.
- Isothermal Custom Limit Temperature: Allows setting specific temperature ranges for analysis.
- Digital Zoom: 2x and 4x digital zoom for detailed inspection.
4. Maintenance
4.1 Cleaning
Regularly clean the device's exterior with a soft, damp cloth. For the lenses, use a specialized lens cleaning cloth and solution to avoid scratches. Do not use abrasive cleaners or solvents.
4.2 Storage
When not in use for extended periods, store the thermal imager in a dry, cool place, away from direct sunlight and extreme temperatures. Ensure the lens protection cover is closed.
4.3 Battery Care
To prolong battery life, charge the battery regularly, even if the device is not in frequent use. Avoid fully discharging the battery for long periods.
5. Troubleshooting
- Device does not power on:
- Check if the battery is properly installed.
- Ensure the battery is charged. Connect to a charger and try again.
- Image is blurry or unclear:
- Clean the infrared and visible light lenses.
- Ensure the lens protection cover is fully open.
- Adjust the focus if applicable (UTi260E/UTi320E models are focus-free).
- Cannot connect to Mobile App/PC:
- Verify Wi-Fi is enabled on the device and your mobile device.
- Ensure the Type-C USB cable is securely connected for PC communication.
- Check if the correct drivers or app are installed on your PC/mobile device.
- Temperature readings seem inaccurate:
- Ensure the emissivity setting is correct for the material being measured.
- Avoid measuring through reflective surfaces.
- Allow the device to stabilize in the environment before taking critical measurements.
