Yes. Noise Suppression mode reduces background interference, while manual frequency selection lets you focus on the leak signal. For compressed-air checks, 20–40 kHz is a useful starting band; adjust it as you scan.

This helps you inspect accessible connections during operation and identify where to check more closely. Keep a safe distance from moving parts and follow the equipment’s operating procedures.

Yes. Air entering a vacuum leak can produce high-frequency sound that the TD2e maps onto the visible image. When the hiss is present, scan accessible intake hose joints and vacuum connections under controlled workshop conditions.

The sound marker helps you focus on a particular hose or connection instead of checking the whole engine bay at random. Keep clear of hot and moving parts, then examine the highlighted connection before deciding on a repair.

Yes. Escaping pressurised gas can produce sound that the TD2e locates, helping you narrow the search around accessible joints and valves. It responds to the leak sound rather than identifying the gas chemically, so the useful signal depends on the leak and pressure conditions.

For trained HVAC technicians, this provides a location for a targeted leak check before repair. Use it in non-hazardous areas; the TD2e is not rated for explosive atmospheres.

Yes, for sounds within its 2–100 kHz range. Scan the assemblies while the sound is present and compare where the acoustic image concentrates. Single-source mode highlights the strongest region; Multi-source mode helps you view several stronger sources together.

This helps you choose which assembly to inspect first. Use the highlighted area to focus the mechanical check, rather than replacing components based on the sound map alone.

Yes, where the leak sound has a clear path to the camera. The specified working range is 0.3–60 metres, so you can begin with an overview from an accessible position.

Useful distance depends on sound strength and site conditions. Once you identify a candidate area, move closer where safe to separate nearby fittings and weaker signals. This helps you decide where a closer inspection is worth arranging.

This helps you choose which assembly to inspect first. Use the highlighted area to focus the mechanical check, rather than replacing components based on the sound map alone.

For compressed-air leaks, start around 20–40 kHz. For vacuum leaks, try 30–60 kHz. If the source is unknown, begin with the full 2–100 kHz range, then narrow the band around the signal you want to investigate.

Treat these as starting points. Adjusting the band while watching the image helps you separate the relevant sound from other equipment nearby.
