7.1 Basic Leak Detection Procedure
- Prepare the Area: Ensure the detection area is as quiet as possible to minimize external noise interference.
- Select Frequency: Use the Frequency Selection Knob (3) to choose an appropriate frequency range. Different pipe materials and depths may require different frequencies for optimal sound capture. Experiment to find the clearest leak sound.
- Adjust Sensitivity: Use the Screen Display Sensitivity Adjustment Knob (7) to fine-tune the device's responsiveness. Increase sensitivity for faint sounds and decrease it to filter out excessive background noise.
- Activate Noise Reduction: If background noise is significant, switch the Noise Reduction Switch (6) to position 'B'. This will help filter out ambient sounds and focus on leak frequencies.
- Scan the Area: Place the sensor firmly on the surface above the suspected pipe. Slowly move the sensor along the pipe's path, listening carefully through the headphones for leak sounds. The LCD screen will display numerical values indicating sound intensity.
- Pinpoint the Leak: As you approach a leak, the sound in the headphones will typically become louder and clearer, and the numerical reading on the LCD screen will increase. Mark the point where the sound is strongest and the reading is highest. This indicates the most probable leak location.
- Verify: Re-scan the area around the marked point to confirm the peak sound intensity and narrow down the exact leak position.
7.2 Using the Sensor Handle Silencer Switch
When moving the sensor handle from one point to another, press and hold the silencer switch on the handle. This will temporarily mute the headphones, preventing sudden loud noises that can be uncomfortable or damaging to hearing. Release the switch once the sensor is in its new position to resume listening.
8. Maintenance
Proper care and maintenance will extend the life of your F999L leak detector.
- Cleaning: Wipe the main unit, sensors, and headphones with a soft, dry cloth after each use. Do not use abrasive cleaners or solvents.
- Storage: Store the device and all accessories in the provided carrying case when not in use. Keep it in a cool, dry place, away from direct sunlight and extreme temperatures.
- Battery Care: For long-term storage, ensure the battery is partially charged (around 50-70%). Recharge the battery every few months to prevent deep discharge.
- Sensor Protection: Handle sensors carefully. Avoid dropping them or subjecting them to excessive force.
9. Troubleshooting
If you encounter issues with your F999L, refer to the table below for common problems and solutions.
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Battery is depleted. | Charge the device using the provided charger. |
| No sound in headphones. | Headphones not connected properly; Volume too low; Sensor not connected; Silencer switch engaged. | Ensure headphones and sensor are securely plugged in. Increase volume. Check if the silencer switch on the sensor handle is released. |
| Excessive background noise. | Noise reduction off; High sensitivity setting; Environmental noise. | Activate noise reduction (switch to 'B'). Reduce sensitivity. Try to minimize external noise sources. Adjust frequency. |
| Cannot pinpoint leak location. | Incorrect frequency selection; Insufficient sensitivity; Sensor not making good contact. | Experiment with different frequency settings. Increase sensitivity gradually. Ensure firm and consistent contact between the sensor and the surface. |
| LCD screen not displaying correctly. | Software glitch; Extreme temperature. | Power off and restart the device. Ensure operating within specified temperature range. If problem persists, contact support. |
