CALCULATION OF SPEED CAL FOR ALL SCS 400 CONSOLES
1)
Set MAN/AUTO switch to MAN, POWER switch to ON, MASTER switch to OFF,
and BOOM switches to OFF.
2)
Enter 990 as boom length in key labelled
.
3)
Enter “0” in keys labelled:
4)
Enter SPEED CAL number of 598 [1520] in ley labelled:
5)
Turn MASTER and BOOM 1 switches to ON.
6)
Drive 1 mile. 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.
7)
Read TOTAL ACRES by depressing key labelled:
The TOTAL AREA should read a value of approximately 10.0. If it reads 9.9, 10.0,
or 10.1, the SPEED CAL for your vehicle is correct.
If the TOTAL AREA display reads any other value, divide the SPEED CAL number
by the value observed in TOTAL AREA, then multiply by 10. This will give you the
correct value to enter for the SPEED CAL. Round off to the nearest 3 digit number.
EXAMPLE:
Assume SPEED CAL is 598 and TOTAL AREA reads 9.3.
598 = 64.3 x 10 = 643
9.3
The number to enter for SPEED CAL is 643.
8)
Recheck the new SPEED CAL calculated in Step 7 as follows:
a)
Zero out TOTAL AREA display as in Step 3.
b)
Enter the new SPEED CAL number as in Step 4.
c)
Repeat Steps 5, 6, and 7.
