4.1. Area and Length Measurement
- From the main menu, select the desired measurement mode (e.g., S-Flat for flat area, S-Slope for slope area, Tul for linear distance).
- Walk along the perimeter of the area to be measured or along the line for length measurement. The device will track your movement.
- Agħfas il- Waqfa button to temporarily stop tracking, and Waqfa għal darb'oħra biex terġa 'tibda.
- 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 Vettura 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.
