Entered value allows system to trigger an acoustic alarm at the exact moment when operator must turn to center
the following track, without leaving any unsprayed areas or overlapping areas.
This distance should correspond to tractor steering radius (
a
in Fig. 38), used at field end to revert travel direction
and resume spraying on the nearby track, but value shall be adjusted according to the operator skills and vehicle
speed.
Alarm is triggered ONLY if vehicle travel direction creates an angle wider than 60° compared to the track to
be run through.
HDOP
Fig. 39
"HDOP" is the value by which satellites number and position affect latitude and longitude accuracy; the lower the
value, the higher the accuracy.
Accuracy alarm is triggered when HDOP value measured by the GPS receiver exceeds set threshold: in this case
Skipper LT asks the operator whether to continue job underway (Fig. 39).
We suggest NOT to set values higher than 4.0.
Refer to par. 9.1 for the steps to take during the alarm.
