• Khetho ea Puo: The device supports Chinese and English languages.

Ho robala ka boithaopo: 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.
• Mosebetsi oa ho Rekota: Collects on-site leak sounds for archiving or comparison of multiple leak recordings. The recording time is 10 seconds.
• Mosebetsi oa skrini: Capture screenshots of the display for documentation.
• Lintlha tsa PC 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. Maemo a Kopo
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. Tlhahlobo ea Khatello: 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.

Tlhokomelo

• Ho hloekisa: Use a soft, dry cloth to clean the device and sensors. Do not use abrasive cleaners or solvents.
• Polokelo: Store the device in a cool, dry place, away from direct sunlight and extreme temperatures. Ensure all components are dry before storage.
• Tlhokomelo ea Betri: For long-term storage, charge the battery to approximately 50% every three months to maintain battery health.
• Tlhokomelo ea Sensor: Handle sensors with care to avoid damage. Keep sensor surfaces clean for optimal performance.
• Lintlafatso tsa Software: Sheba ea moetsi website periodically for any available software updates to ensure optimal performance and new features.

Ho batle phoso

• Sesebediswa Ha se Matla: Ensure the battery is sufficiently charged. Connect the device to the charger and try again. If the issue persists, contact support.
• Ha ho na Molumo o tsoang ho li-headphones: Check if the headphones are securely plugged in. Verify the volume settings on the device. Test with another pair of headphones if possible.
• Inaccurate Readings/Excessive Noise: Ensure the sensor is making good contact with the surface. Adjust the gain and frequency range settings to filter out environmental noise. Move to a quieter environment if possible.
• Sesebediswa se Tlama: Try restarting the device by holding down the power button. If it remains unresponsive, allow the battery to fully discharge and then recharge before attempting to power on again.
• PC Connection Issues: Ensure the Type-C cable is properly connected to both the device and the computer. Verify that the “PC data viewing” function is enabled in the device settings. Try a different USB port or cable.
