• Výběr jazyka: The device supports Chinese and English languages.

Automatické uspání: Configure auto-sleep settings for 10, 15, or 30 minutes to conserve battery life. 

4.2. Leak Detection Modes
The UT662 series offers various modes to assist in precise leak detection:

• Quick Check Mode: Displays all sound signals within the frequency response range and their frequency spectrum. This allows for rapid localization of the approximate leak point. You can switch between bar graph and line graph displays.
• Inspection Mode: The instrument displays a bar graph collection interface. Move the sensor across the suspected area. Click on the corresponding signal bar to start collecting signals. Compare the collected signal bars to accurately locate the leak point.
• AI Intelligent Leak Detection: This mode effectively removes pipeline noise and environmental interference, accurately identifying the sound of water leakage. In quick check mode, click the “AI” icon for the device to intelligently determine and display abnormal signal points (blue bars).
• Multi-band Frequency Range: In quick check mode, the instrument can set multiple frequency ranges to adapt to different leak scenarios. Adjust high, mid, and low bands to exclude other frequency interferences. Manual adjustment is also possible in full-band mode.
• Effective Volume Display: Displays effective volume, excludes environmental noise, and focuses on leak volume. Effectively shields impact sounds and other noises, highlighting leak sounds and suspected leak sounds.
• Funkce nahrávání: Collects on-site leak sounds for archiving or comparison of multiple leak recordings. The recording time is 10 seconds.
• Funkce snímku obrazovky: Capture screenshots of the display for documentation.
• PC data Viewing: Enable the “PC data viewing” function in settings. Connect the device to a computer via USB to view captured screenshots and recording files.

4.4. Aplikační scénáře
The UT662 series is suitable for various leak detection applications:

• Indoor buried pipe leak detection
• Underfloor heating pipe leak detection
• Cabinet body pipe leak detection
• Outdoor pipe leak detection

4.5. Combining with Thermal Imager for Underfloor Heating Leak Detection
For underfloor heating systems, the UT662 can be used in conjunction with a thermal imager for enhanced precision:

1. Kontrola tlaku: Apply pressure to the underfloor heating pipes to confirm if there are pressure drops or leaks.
2. Hot Water Injection: Inject hot water (70°C or above) into the pipes. Wait approximately 15 minutes for the heat to transfer to the ground surface.
3. Thermal Imaging Scan: Use an infrared thermal imager to scan the floor surface to detect the path of the pipes and identify potential leak areas. Leak points may appear as distinct thermal clusters or areas with unusual temperature patterns.
4. UT662 Fine-tuning: Once a suspected leak area is identified by the thermal imager, use the UT662 series leak detector in that specific region. Analyze the frequency waveform and sound values. A clear change in waveform, higher sound frequency, and louder leak sound indicate the precise leak point.
5. Mark and Repair: After accurately locating the leak point, mark the area for excavation and repair.

Údržba

• Čištění: Use a soft, dry cloth to clean the device and sensors. Do not use abrasive cleaners or solvents.
• Skladování: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure all components are dry before storage.
• Péče o baterie: For long-term storage, charge the battery to approximately 50% every three months to maintain battery health.

Tipy pro uživatele

• Jazyková podpora: The device menu is available in Chinese and English only. Portuguese (Brazil) is not supported.
• Optimal Detection: For best results, ensure the sensor is placed firmly on the surface being inspected. Minimize ambient noise as much as possible.
• Podlahové topení: When detecting leaks in underfloor heating, injecting hot water (above 70°C) and waiting for about 15 minutes can significantly improve the accuracy of detection, especially when combined with a thermal imager.
