Startup, Initial Setup and Setup Wizards
Offsets
The antenna offset is used to calibrate the field
computer for the relative location of the center of the
boom or implement with respect to the GPS antenna.
Note:
The field computer will not recognize a
negative value for any of the antenna offset
values. Be sure to enter positive values for
each offset setting. All negative values
entered will be reset to ‘0’.
The Raven Offsets Setup screen displays the currently
calibrated values for the following antenna offsets:
• Fore/Aft
• Left/Right
• Height
Fore or Aft Offset
The fore/aft offset is the distance of the boom or implement in front or behind the GPS antenna.
Note:
The fore/aft offset must be measured perpendicular to the boom or implement width. See Figure 1
below.
To set the fore/aft value:
1. Touch the current fore/aft value displayed on the Raven Offsets Setup screen.
2. Use the keypad to enter the measured fore/aft value in inches (U.S.) or centimeters (Metric).
3. If the boom or implement is in front of the GPS antenna, select the ‘Implement in Front’ option.
