Measuring Way Of Handheld GPS Survey Equipment:
First, press up and down button to choose a measuring mode;
1. Normal mode : at the starting point, press [Start/Stop] button to measure in the main surface; return to the starting point in a circle around the
ground, press the [Start/Stop] button to pause the measurement data. Press the "power" button to end measurement and save data.
2. Circle Machine Load :First, set Circle value number in Parameter setting. And put this equipment in the car from a position which is the nearest
to the edge. Press [Start/Stop] button to start measuring while working.Press [Start] to go on when it’s not finished. Press the "power" button to
end measurement and save data.
3. Fixed Width Mode : First, set width number in Parameter setting. And press [Start/Stop] button to start measuring at the starting point. Walk to
the under line then press [Start/Stop] button to pause and check the data; press the "power" button to end measurement and save data.
4. Fixed pointed Mode : at the starting, press [Start/Stop] button to start measurement, then press [enter] button to make one corner point; then
walk along the edge to the next corner, and press [enter] button at every corner to collect information of each corner. At last, press the [
Start/Stop] button to view the measurement data; press the "power" button to end measurement and save data.
5. L/W mode : at the starting point , press the [Start/Stop] button to measure,and press the [enter] button to save information; Going from point to
another point, press the [enter] button to save information; then going from this point to the finial point, press the [enter] button to save
information; at last, press the [Start/Stop] button to view the measurement data; press the "power" button to end measurement and save data.
6. Round-trip Machine Load : In this mode, you could measure the area while the farm machine’s working. First, set the value number in
Parameter Round-trip setting. Then press [Start/Stop] button to start measuring while working. Press [Start/Stop] button to check when
working is done. Press [Start] to go on when it’s not finished. Press the "power" button to end measurement and save data.
7. Normal distance Mode : In this mode you can do distance measurement, at the starting point, press the [Start/Stop] button to start measuring.
And walk along the measuring line to the final point. Press the [Start/Stop] button when you reach the final, press the "power" button to end
measurement and save data.
8. MultiPoint Mode : In this mode you can do distance measurement that fits all kinds of flat terrain. At the beginning, press [enter] button to save
starting point, walk to the next point and press [enter] to save this point; press the "power" button to end measurement and save data.
