PQWT support FAQ

Common questions about manuals, registration, and support for this brand.

  • How do I pinpoint a leak using a PQWT detector?

    Use the Filtering Analysis mode after a rough scan. Look for a stable, high-intensity signal bar (thick line) on the display, which indicates continuous leakage noise, unlike fluctuating environmental noise.

  • What sensors should I use for different ground types?

    PQWT detectors often come with multiple sensors. Use the specific listening stick sensor for soft soil areas, and the standard triangular or round sensors for hard surfaces like concrete or tiles.

  • How does the device filter out background noise?

    The equipment uses frequency spectrum analysis to distinguish between the continuous sound of a leak and intermittent external noises. Ensuring a quiet environment during detection improves accuracy.

  • Can I record the sounds I hear during detection?

    Yes, many models support a Live Recording function to capture underground sounds, allowing you to replay and analyze suspected leak points later.
