7. Emissivity Adjustment
Emissivity can be adjusted from 0.01 to 1.00 (default: 0.95) according to the material of the object being measured. Correct emissivity settings ensure more accurate temperature readings.
8. PC Analysis Software
The UTi120S+ is equipped with professional infrared analysis software (UTi Thermal Pro). After connecting the device to a computer via the Type-C USB cable, you can browse and analyze stored infrared images and export PDF reports.
Maintenance
1. Cleaning
- Wipe the device body 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.
2. Battery Care
- Recharge the battery when the low battery indicator appears.
- If storing the device for an extended period, charge the battery to approximately 50% and recharge every few months to maintain battery health.
3. Storage
- Store the device in a cool, dry place, away from direct sunlight and extreme temperatures.
- Keep it in its original packaging or a protective case to prevent damage.
Troubleshooting
- Device does not power on: Ensure the battery is charged. Connect to a power source and try again.
- Inaccurate temperature readings:
- Check and adjust the emissivity setting according to the material being measured.
- Ensure the measurement distance is appropriate (minimum 0.5m).
- Clean the infrared lens if it appears dirty.
- Image is blurry or unclear:
- Ensure the lens is clean.
- Check if the Super Resolution feature is enabled for clearer images.
- Alarm not triggering: Verify that the high/low temperature alarm thresholds are correctly set in the device menu.
