CALCULATING "SPEED CAL"

1)

Place a chalk mark or tape onto the vehicle tire that the Speed Sensor mounted

to it as shown below.

2)

Mark the initial spot on the ground.

3)

Drive vehicle straight ahead counting 10 full revolutions of the wheel.  The mark

must stop at the same position it was in when the vehicle started.

4)

Measure the distance from the ground starting mark to stopping mark in inches [dm]

(Round off fractions).

5)

Write down this distance as the SPEED CAL number; keep it for future reference

when programming the Console.

NOTE:

This measurement is critical to the performance of the Console.

 MEASURE

CAREFULLY

.  Be sure tire is properly inflated before measuring.  Measure

tire in type of soil in which you will be spraying.  Circumference of

tire will vary when measured in soft soil versus hard packed soil.  For

best results, measure several times and average the results.

6)

It may be necessary to modify your SPEED CAL number based on the amount of magnets

you are using.  The SCS 330 software assumes that 2 magnets are mounted on the

wheel.  If more than 2 magnets are used, the following calculation must be made.

EXAMPLE:

Assumed # of magnets

= 2

Actual # of magnets

= 6

Current SPEED CAL

= 612 [155]

Corrected SPEED CAL =

Assumed # of magnets x current SPEED CAL

    Actual # of magnets

ENGLISH UNITS:

METRIC UNITS:

= 2 x 612 = 204

= 2 x [155] = [51.6]

     6

6

Corrected SPEED CAL is 204 [52]
