4. Operating Instructions
The Mileseey GPS Land Meter offers various measurement functions accessible via its intuitive interface.
4.1 Navigation and Menu
Use the directional buttons (up, down, left, right) to navigate through menu options. The 'OK' button confirms selections, and the 'Power' button often serves as a back/cancel function in menus.
4.2 Measurement Modes
The device supports two primary measurement modes:
- Handheld Measurement: Hold the land meter and walk along the boundaries of the area to be measured. The device will automatically calculate the area.
- Autocar Measurement: Place the land meter in the middle of a vehicle (e.g., tractor). After setting the width of the vehicle, the device will automatically calculate the area enclosed by the boundary that the vehicle passes through.

4.3 Types of Measurement
The device can perform various types of measurements:
- Area Measure:
- Flat Area: For regular or irregular flat land.
- Brae Area (Hillside): For measuring sloped terrain.
- Acquilate (Equilateral/Regular): For areas with predefined geometric shapes.
- Round Point: For circular areas.
- Rectangle: For rectangular areas.
- Mode 1: Measurement along the action path (walking the perimeter).
- Mode 2: Rotation measurement along the ground (for agricultural machinery).
- Length Measure: For measuring straight or curved distances.
- Speed Measure: Measures the current speed of movement.
