SWATH CALIBRATION
The Swath Calibration feature is an aid for very accurate swathing requirements. The DGPS
Receiver accuracy is high for short periods of time. When long time intervals occur during
swathing, small across track position drifts can be corrected using Swath Calibration. The
machine operator must be able to determine the precise corrected position of the current
swath line and position the machine to that point. Swath Calibration will adjust the AB line
reference and all successive swaths to this adjusted point. Swath Calibration is limited to 1/4
the current swath width setting. From the Swath Navigation screen, press and hold the MENU
button for approximately 3 seconds. When the [CAL...SWA] screen shows, the MENU button
may be released. Press the SELECT button to calibrate the swath line to the current position
or press the MENU button to return to the Swath Navigation screen without changing the
swath calibration.
The swath calibration limit may be turned off. In the SYS configuration menu, set DSP to CFG
then in the DSP configuration menu, set DSP-LSC to OFF. When LSC-ON, the Swath Calibra-
tion is limited to 1/4 of the current swath width setting. When LSC-Off, the Swath Calibration
limit is bypassed.
SPECIAL OFFSET AND ANGLE DISPLAYS
Special offset and angle LED display patterns indicate that the Smartbar is nearly perpendicu-
lar to swath line. This display pattern will usually be seen only when turning from one swath to
another or when leaving and returning from a ‘Saved Position’.
See the diagram “An Ideal Turn” on page 57 for an illustration of how the angle LED’s indicate
swath alignment between 70
o
and 110
o
(20
o
on either side of 90
o
, which is perpendicular).
Notice the angle LED’s are all on (either left or right) from about 15
o
to about 70
o
. As the
swath angle increases toward perpendicular, an additional angle LED will come for each 5
o
until all angle LED’s are ON at 90
o
. As the swath angle continues to increase, beyond 90
o
,
an angle LED will go off for each 5
o
until all angle LED’s on the original side are off. As the
angle changes toward swath alignment, LED’s will begin to go off at about 15
o
(referenced to
the next swath line) and will all be off when alignment to the next swath is reached.
Angle LED display patterns between 70
o
and 110
o
are shown in the following table.
