Measuring Methods of GPS land 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. Normal distance mode:at the starting point, press [Start/Stop]
button to start measuring ;Walk along the measuring line to the end
point and
press the [Stop] button to stop the measurement and view the
measurement data;If the measurement is not completed,press
the[Start] button
again to continue the measurement. If the measurement is
completed,press "power" button to save the data.
3. Multi-point mode:At the land starting point,press the up and
down button switch function to “Multi-point Distance ”.Press the
[Start] button to
start measuring.Then press the [Enter] button to collect the
information of the points.Finally,press the [Stop] button to stop
the measurement
and view the measurement data; If the measurement is
completed,press "power" button to save the data.
4. Mountain Mode : at the mountain top, press [Start/Stop] button
to start measuring the mountain area.Now, it is the point A; Reach
to the bottom
of the mountain, it is the point B. Press the [enter] button to
save point B information; then walk around the bottom of the
mountain, press
[enter] button when you finished. press the [Start/Stop] button to
pause the measurement data, [start] to go on and press the "power"
button to
end measurement and save data.
5. Intell Slope : at the starting point, press [Start/Stop] button
to measure in the main surface; walk around the slope and press the
[Start/Stop]
button when you finished. Press the [Start/Stop] button to pause
the measurement. 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. Slope Mode : Set slope in Parameter setting before measuring.
Then press [Start/Stop] button to measure in the main surface; walk
around
the slope and press the [Start/Stop] button when you finished.
Press the [Start/Stop] button to check the measurement data. Press
the
"power" button to end measurement and save data.
