6. الإعداد الأولي والمعايرة
The NF-518S features an automatic calibration function for its wall scanning modes. This ensures accurate detection results without manual adjustment.
- تشغيل الطاقة: اضغط مع الاستمرار على زر التشغيل لتشغيل الجهاز.
- المعايرة التلقائية: When switching to a wall detection mode, place the device flat against the wall surface where you intend to scan. The device will automatically calibrate itself. Ensure there are no objects or wires directly beneath the device during this initial placement to avoid false readings.
- اختيار الوضع: Use the 'SURVEY' button to cycle through the different wall detection modes (Wood, Metal, AC Wire). Use the 'DIST' button to cycle through laser measurement modes.
7. أوضاع التشغيل
The NF-518S offers three primary operating modes: Stud Finder, Laser Distance Meter, and Digital Level.
7.1. Stud Finder Operation (Wall Detection)
This mode is used to detect wood studs, metal objects (magnetic and non-magnetic), and live AC wires behind walls.
Image 7.1.1: The NOYAFA NF-518S illustrating its capability to detect metal, copper, wood, and wire at various depths within a wall structure.
- حدد الوضع: Press the 'SURVEY' button to select the desired detection mode:
- Wood Stud Scan: Detects wood studs at depths of 1/2", 1", and 1.5".
- فحص المعادن: Detects non-magnetic metals up to 2.4 inches deep and magnetic metals up to 3.2 inches deep.
- فحص مكيف الهواء: Identifies live unshielded wires up to 2 inches deep.
- الموقع: Place the device flat against the wall surface. Ensure the device is fully calibrated (as described in Section 6).
- مسح: Slowly slide the device horizontally across the wall surface. Keep the device flat against the wall without lifting or tilting.
- Detection Indication: The LCD display will show visual indicators (e.g., signal strength bars, object type icon) and an audible alert when an object is detected. The center of the object will be indicated on the screen.
- العلامة: Use the marking hole on the device to precisely mark the location of the detected object.
ملحوظة:
- Detection depth and accuracy can be affected by wall material, moisture content, and other environmental factors.
- Always scan the area multiple times from different directions to confirm detection.
7.2. Laser Distance Meter Operation
This mode allows for precise distance measurements and various calculations.

10. استكشاف الأخطاء وإصلاحها
- الجهاز لا يعمل:
- تأكد من شحن البطارية. وصّل الجهاز بمصدر طاقة باستخدام كابل Type-C، ثم حاول مرة أخرى.
- Inaccurate stud/object detection:
- Ensure the device is properly calibrated by placing it flat against the wall before scanning. Scan slowly and consistently. Wall materials, moisture, and nearby electrical interference can affect accuracy. Try scanning from different angles.
- Laser measurement errors:
- Ensure the laser emitter and receiver are clean. Measure to a flat, non-reflective surface. Avoid obstructions in the laser path.
- العرض باهت أو غير قابل للقراءة:
- Check battery level. The device has a backlit display for improved visibility in low light conditions.
