Speed Cal
The current speed cal is displayed on the Speed Cal button. Touch the Speed Cal button and use the on-
screen keypad to enter a speed cal value.
Raven Industries 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 the specific vehicle and speed sense system. See Appendix A,
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.
Test Speed
The test speed may be used to simulate speed when testing or troubleshooting the product control system.
Enter a value approximately equal to normal application speeds to allow the field computer to control product
application functions while the vehicle remains stationary. The test speed is useful for troubleshooting the CAN
and product control systems.
Note:
A speed cal must be entered to allow the test speed feature to function.
The test speed area displays the current test speed. Touch this area to enter a test speed.
Note:
The test speed will clear if the field computer receives a pulse from the actual speed sensor. To
keep the test speed from disengaging, disconnect the speed sensor from the system.
Distance
The distance value can be used as an odometer of the distance traveled by a vehicle over a season, or the
distance traveled during one application. Touch the Reset Value button to clear the distance value, or allow the
field computer to keep a running tally of the total distance traveled.

NOTICE
When using the GPS speed over CANbus
feature, no tuning or adjustment is necessary or
recommended to the speed cal value. Losing
GPS signal for more than a second will also
result in loss of the CAN speed signal which
may affect product application in progress.
