- Screen is blank or frozen: Try restarting the device by holding down the power button. If unresponsive, allow the battery to fully discharge and then recharge before attempting to power on again.
- Inaccurate temperature readings: Verify that the emissivity setting is correctly adjusted for the material you are measuring. Ensure the lens is clean and free from obstructions.
- WiFi connection issues: Ensure the camera's WiFi is enabled and your mobile device is within range. Double-check the network name and IP address (192.168.230.1).
- Images not saving: Check if the internal storage is full. Transfer existing images to a computer to free up space.
If problems persist, please contact customer support.
10. User Tips
- Emissivity Settings: For the most accurate temperature measurements, always adjust the emissivity setting to match the material surface you are inspecting. Different materials emit infrared energy differently. Consult an emissivity table for common materials.
- Optimal Viewing: Experiment with different color palettes to find the one that best highlights the temperature differences relevant to your inspection.
- Regular Data Transfer: Periodically transfer your saved images to a computer to back them up and free up internal storage space on the device.
