Calculating the
Calibration Values
Speed Cal
Raven industries recommends the following values for the initial speed cal:
These values are usually a good starting point and will generally yield adequate results; however, the speed cal
should still be refined for each vehicle.
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.
1. Make sure any section switches are turned OFF before powering the console ON.
2. In the System menu, touch the Product Control icon and touch the Speed button.
3. Touch the Distance button and then reset the odometer display to “0” using the keypad.
