Mountain Mode Measurement:
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.
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.
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.
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.
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.
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.
Shutdown:
Press the button for about 2 secs and the shutdown page appears,
press the [enter] button to confirm the shutdown.
