4.3 Infrared Imaging Palettes
The TR120 offers 6 distinct color palettes to visualize thermal data, allowing you to choose the best representation for your specific application and visual comfort. These palettes include:
- High Resolution Rainbow
- Vermell Calent
- Lava
- Arc de Sant Martí
- Òxid de ferro vermell
- Calor blanca

4.4 Automatic Hot/Cold Spot Tracker
The device features an automatic hot/cold spot tracker that highlights the areas of maximum and minimum temperature on the screen. This allows for quick identification of critical temperature points and provides warnings for high or low temperatures based on user-defined settings.

4.5 Saving Pictures
To save a thermal image, simply press the designated one-button operation. The device has a large internal memory capable of storing up to 2000 high-definition pictures for later review i anàlisi.

4.6 Data Export to PC
Connect the TR120 to your computer using the Type-C USB cable. This allows you to export saved images and data for more detailed analysis on a larger screen or for reporting purposes.

4.7 Emissivitat ajustable
Emissivity is a measure of an object's ability to emit infrared energy. Different materials have different emissivity values. To ensure accurate temperature readings, adjust the emissivity setting on the TR120 to match the material you are inspecting. Refer to common emissivity tables for guidance.

4.8 Powerful LED Light
For inspections in dimly lit or dark environments, activate the powerful LED light. Its adjustable brightness ensures clear visibility of the inspection area, enhancing safety and accuracy.

5. Manteniment
5.1 Neteja
Regularly clean the device, especially the lens and display, using a soft, dry, lint-free cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the device's surfaces or optical components. Ensure the lens is free from dust, smudges, and debris for optimal thermal imaging performance.
5.2 Emmagatzematge
When not in use, store the Mileseey TR120 in a cool, dry place, away from direct sunlight, extreme temperatures, and high humidity. If storing for extended periods, ensure the battery is charged to approximately 50% to prolong its lifespan. Use the original packaging or a protective case to prevent physical damage.
5.3 Cura de la bateria
To maximize battery life, avoid completely discharging the battery frequently. Recharge the device regularly, even if it has not been used for a while. If the device will not be used for an extended period, charge it to about 50% every few months.
6. Solució De Problemes
| Problema | Causa possible | Solució |
|---|---|---|
| El dispositiu no s'encén | La bateria està descarregada. | Connect the device to a power source using the Type-C USB cable and charge it. Try powering on again. |
| Lectures de temperatura inexactes | Incorrect emissivity setting; dirty lens; highly reflective surface. | Adjust the emissivity setting to match the material being measured. Clean the lens with a soft, dry cloth. Avoid measuring highly reflective surfaces directly or apply a non-reflective coating. |
| No es pot connectar a l'ordinador | Loose USB connection; faulty cable/port; device not in data transfer mode. | Ensure the USB cable is securely connected. Try a different USB port or cable. Verify the device is powered on and in the correct mode for data transfer (if applicable). |
