4.2 Étalonnage initial
For accurate results, the device must be calibrated before each use or when changing scanning locations.
- Appuyez sur le bouton d'alimentation pour allumer l'appareil.
- Place the device flat against the wall surface where you intend to scan, ensuring there are no known studs, metal, or wires in that specific spot.
- Press and hold the Mode Selection button (or the dedicated calibration button if present, refer to display for indication) until the calibration process is complete (usually indicated by a beep or a stable display reading).
- The device is now calibrated and ready for use.
5. Mode d'emploi
The LiebeWH HW-QB6 offers multiple detection modes for various materials. Select the appropriate mode for your task.
5.1 Sélection d'un mode de détection
Press the Mode Selection button to cycle through the available modes. The selected mode will be indicated on the LCD display.
- Numérisation des montants en bois : For locating wood studs and joists.
- Scan des métaux : For detecting metal objects such as rebar, pipes, and metal conduit.
- AC Wire Scan: For identifying live unshielded AC electrical wires.
5.2 Procédure de numérisation
- Ensure the device is calibrated as described in Section 4.2.
- Placez l'appareil à plat contre la surface du mur.
- Slowly slide the device horizontally across the surface. Maintain constant contact with the wall.
- Consultez l'écran LCD pour obtenir des indications sur les objets détectés.
- When an object is detected, the signal strength indicator will increase, and an audible alert may sound. The "CENTER" indicator will illuminate when the device is directly over the center of the object.
- Mark the edges and center of the detected object for accurate positioning.

5.3 Interpreting the LCD Display
- Barres de puissance du signal : Indique la proximité d'un objet détecté. Plus il y a de barres, plus la proximité est grande.
- Indicateur CENTRAL : Appears when the device is directly over the center of a stud or object.
- Icône de mode: Displays the currently selected detection mode (e.g., wood icon, metal icon, AC lightning bolt icon).
- Indicateur de batterie : Shows the current battery level. Replace batteries when low.
- Depth Indication (if applicable): Some models may show an approximate depth. Refer to the specific icons on your display.
6. Entretien
- Nettoyage: Essuyez l'appareil avec un chiffon doux, damp chiffon. N'utilisez pas de nettoyants abrasifs ou de solvants.
- Stockage: Rangez l'appareil dans un endroit frais et sec, à l'abri de la lumière directe du soleil et des températures extrêmes. En cas de stockage prolongé, retirez la batterie pour éviter toute fuite.

7. Dépannage
| Problème | Cause possible | Solution |
|---|---|---|
| L'appareil ne s'allume pas. | Batterie déchargée ou mal installée. | Vérifiez la polarité de la pile. Remplacez-la par une pile 9V neuve. |
| Lectures inexactes ou incohérentes. | Improper calibration; device not flat against wall; wall material too thick/dense; presence of moisture. | Recalibrate the device. Ensure constant, flat contact. Test on a different wall section. Avoid scanning wet areas. |
| AC wire detection is inconsistent. | Wires are shielded; wires are too deep; low battery. | AC detection works best for unshielded, live wires. Ensure battery is fresh. Scan slowly. |
| No detection in Wood/Metal mode. | No objects present; object too deep; incorrect mode selected. | Ensure correct mode is selected. Scan slowly and thoroughly. Consider wall thickness limitations. |
