4. Instrukcja obsługi

The PQWT L3000 offers two primary detection modes: General Detection and Locating Mode.

4.1. General Detection (Outdoor)

General Detection is primarily used for checking large outdoor pipeline areas for water leakage.

1. Enter Outdoor Mode: On the host machine, click to enter the "Outdoor" mode.
2. Select Soil/Pipe Type: Select the soil texture (e.g., "Hard") and pipe material (e.g., "Metal") according to your detecting environment.
3. Start General Detection: Click "General Detection" to enter the interface.
4. Czujnik położenia: Place the sensor above the suspected pipe area.
5. Receive Sound: Turn on the knob switch to receive sound through the headphones.
6. Observe Spectrum: Listen to the volume and observe the spectrum change on the screen. Move the sensor forward, detecting points in the same way.
7. Identify Leakage Area: When the spectrum on the instrument screen is high and the sound in the headset is significantly increased, the area can be identified as a suspected leakage area and marked.

4.2. Locating Mode (Outdoor)

Locating Mode is used to pinpoint leak points within suspected leakage areas.

1. Enter Locating Mode: On the host machine, click to enter the "Locating" mode.
2. Start Detection: In the suspected leakage area, start detection from the first point.
3. Click Spectrum Bar: Click any position in the spectrum bar. The signal value will be displayed on the top of the spectrum bar. The thin bar represents ambient noise, while the thick bar represents underground sound.
4. Lock Stable Signal: After the thick bar is stable, click again any position in the spectrum bar to lock it. The signal value changes from red to black, indicating the detection at that point is completed.
5. Compare Points: Use the same method to compare different points in this area. The detection point with the highest thick spectrum bar and the largest signal value is the suspected leaking point.
6. Eksportuj dane: Detection reports in locating mode can be stored after clicking the "Export" button and connecting to a computer.

4.3. General Detection (Indoor)

General Detection is used for checking large indoor pipeline areas for water leakage.

1. Enter Indoor Mode: On the host machine, click the "Indoor" icon, then choose "General Detection".
2. Receive Sound: Turn on the knob switch to receive sound through the headphones.
3. Observe Spectrum: Listen to the volume and observe the spectrum change on the screen. Move the sensor forward, detecting points in the same way.
4. Identify Leakage Area: When the spectrum on the instrument screen is high and the sound in the headset is significantly increased, the area can be identified as a suspected leakage area and marked.

4.4. Locating Mode (Indoor)

Locating Mode is used to pinpoint leak points within suspected indoor leakage areas.

1. Enter Locating Mode: On the host machine, click to enter the "Locating" mode.
2. Start Detection: In the suspected leakage area, click any position in the spectrum bar.
3. Lock Stable Signal: After the thick bar is stable, click again any position in the spectrum bar to lock it. The detection point with the highest thick spectrum bar and the largest signal value is the suspected leaking point.

5. Konserwacja

• It is forbidden to put the sensor into the water. Please handle the sensor gently.
• It is forbidden to use the device in flammable and explosive areas such as gasoline and natural gas.
• If the instrument is not used for a long time, please charge it once a month at least to maintain battery health.
• When detecting in areas with soft soil or a lawn, it is recommended to use the sensor connected to the sound pole and insert it into the soil for optimal results.

6. Rozwiązywanie Problemów

While no specific troubleshooting section is provided, ensure the following if you encounter issues:

• Sprawdź połączenia: Verify all sensors, headphones, and cables are securely connected to the host machine.
• Poziom naładowania baterii: Sprawdź, czy urządzenie jest odpowiednio naładowane.
• Parametry środowiskowe: Confirm that the correct soil texture and pipe material are selected in the settings for accurate detection.
• Rozmieszczenie czujnika: For soft ground, ensure the sound pole is properly inserted.
• Zakłócenia hałasu: Utilize the noise reduction headphones and adjust frequency settings as needed to minimize environmental interference.
