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