4. دليل التشغيل

The NF-198 offers various measurement modes and functions accessible via its main menu.

Figure 4: Main Menu Functions

This image displays the main menu of the NF-198, showing icons for S-Flat (flat area measurement), Length, S-Slope (slope area measurement), S-Width (width measurement), Vehicle (vehicle-carrier measurement), and Query (data query).

4.1. Area and Length Measurement

1. From the main menu, select the desired measurement mode (e.g., S-مسطحة for flat area, المنحدر S for slope area, طول for linear distance).
2. Walk along the perimeter of the area to be measured or along the line for length measurement. The device will track your movement.
3. اضغط على يوقف button to temporarily stop tracking, and يوقف مرة أخرى لاستئناف.
4. Once the measurement is complete, the device will display the measuring value, figure track, and automatically calculate the price if configured.

This image shows the NF-198 screen displaying measurement results, including Girth, S-Flat area, Piece, Total, and GPS coordinates (LON, LAT), along with the date and time.

4.2. Vehicle-Carrier Measurement

This mode allows for distance measurement while mounted on a vehicle. The distance can be adjusted according to specific needs. Select عربة from the main menu to activate this function.

4.3. Equal-Width Area Measurement

This function is used for measuring areas with a consistent width. Consult the on-screen instructions or specific manual section for detailed steps on using this mode.

4.4. Setting Unit Area Price

The device allows you to set a unit area price, enabling automatic price calculation after measurement. This can be done via 'manual testing' or 'auto testing' methods.
