4.
Touch the Speed Cal value and use the on-screen keypad to enter the new value.
Raven recommends the following speed calibration values for initial system setup.
These values are good starting points and generally yield adequate results, however, the speed cal should
be refined for each specific vehicle and speed sense system. See Appendix B,
Calculating the Calibration
Values , for instructions on refining the speed cal value.
Note:
The GPS speed over CANbus feature is only available with specific Raven speed sense nodes.
This feature utilizes NMEA speed over ground data transmitted over the CAN network which
eliminates the need for a separate, external speed sensor.
If another source will be used to detect vehicle speed, touch the Calibration Assistance button
and follow the on-screen instructions. Refer to Appendix B, Calculating the Calibration Values for
additional information about the calibration assistance procedure. The procedure outlined in Using
the Calibration Assistance section on page 245, should also be performed to refine or verify the
initial value used with a speed sensor not listed in the above table.
