5.2. Conducting a Survey
The PQWT M200 offers high-speed and efficient detection of underground water sources. It is suitable for various geological structures including plains, hills, mountains, highlands, and basins.
- Selezionare la modalità di misurazione: In the software operation interface, choose your desired measurement mode (e.g., "Three frequency" for rough tests or "Profile survey").
- Imposta parametri: Adjust parameters such as "Lines", "Sites", and "Gain" as needed. Click "OK" to confirm.
- Inizia la misurazione: Click "Record" to begin measuring the first point.
- Continue Measurement: After the data for the first point is measured and the app indicates "record completed", move to the next measurement point and click "Record" again. Repeat this process for all desired points.
- Analisi dei dati: The instrument automatically generates geological section drawings without the need for a computer (Android system only). Analyze the generated curves and maps to identify potential water locations.
