CONSOLE CALIBRATION
1. CALCULATING "BOOM CAL"
Enter the total width of the spread pattern in inches [cm] as boom length (See
"Definition of Boom Calibration keys").
2. CALCULATING "SPEED CAL"
Initial SPEED CAL is 598 [152]. Complete Steps 1 thru 6 to refine this number
after section "INITIAL CONSOLE PROGRAMMING" has been completed.
1) Set POWER switches to ON, all other switches to OFF.
2) Enter "0" in key labelled
3) Drive 1 mile [1 kilometer]. To achieve the most accurate calibration, accelerate
and decelerate slowly.
CAUTION: Do not use vehicle odometer to determine distance. Use section
lines or highway markers.
4) Read DISTANCE by depressing key labelled
DISTANCE should read a value of approximately 5280 [1000]. If it reads between
5260-5300 [990-1010], the SPEED CAL for the vehicle is 598 [152]. If the DISTANCE
display reads any other value, perform the following calculation:
EXAMPLE: Assume DISTANCE reads 5000 [980].
Corrected SPEED CAL = Old SPEED CAL x 5280
DISTANCE
ENGLISH UNITS: METRIC UNITS:
= 598 x 5280 = 631.48 = [152] x [1000] = [155]
5000 [980]
5) The number to enter for SPEED CAL is 631 [155].
6) Recheck the new SPEED CAL derived in Step 5 by repeating Steps 2 thru 5.
