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.
