Console Programming and Calibration
9. Use the arrow keys to advance to the remaining booms and enter the data for each boom.
Note:
If a boom is not being used, enter 0 for the boom length.
10. Press the SPEED CAL button and enter the appropriate speed cal value for the type of sensor being used.
Note:
The SPEED CAL value will have to be calibrated if Raven radar is not being used.
11. Press the METER CAL button and enter the meter cal value stamped on the flow meter’s identification tag.
12. Press the VALVE CAL button and enter the calibration number that corresponds with the control valve being
used.
13. Press the RATE 1 CAL button and enter the Rate 1 value that was previously calculated.
14. Press the RATE 2 CAL button and enter the Rate 2 value that was previously calculated.
Important: The Rate 2 value should not vary by more than 20% from the Rate 1 value, or the spray
pattern may suffer. If a second rate is not being used, enter the same value that was entered
for the Rate 1 Cal.
The initial console programming is now complete, and the flashing “CAL” in the console’s display should turn
off. If it does not, repeat the procedure starting from step 7 above.
Refining the Speed Cal Value - Raven Radar Only
The initial Speed Cal value when using Raven radar is 598 [152]. However, after initial console programming, it
may be necessary to refine this number to improve the system’s performance. Complete the following steps to
refine the speed cal value:
1. Turn the POWER switch ON.
2. Turn all boom switches OFF.
3. Press the DISTANCE button on the SCS 450 console.
4. Enter 0 as the value.
5. Drive 1 mile [1 km].
Note:
Do not use the vehicle’s odometer to determine the distance. Use highway markers or section
lines to measure the distance traveled. To achieve the most accurate calibration, accelerate and
decelerate slowly using typical application speeds.
6. Press the DISTANCE button. The value should be approximately 5280 [1000]. If the value is between 5260
- 5300 [990 - 1010], the speed cal value for the machine is 598 [152]. If the value is any other value, use the
following formula to recalculate the speed cal value.
For Example:
Assume that the DISTANCE value is actually displayed as 5000 [980].
Important: The new Speed Cal value must be rounded to the nearest whole number.
Old SPEED CAL X 5280 = Adjusted Speed Cal
DISTANCE VALUE
598 X 5280 = 631.48 (English)

[152] x [1000] = 155 [metric]
