For Example:
Speed Cal = 612 [155]
Actual Distance = 5280 [1000]
Field computer odometer reading = 5000 [980]

Metric Units:
The Corrected Speed Cal value is 646 [158].
5. Touch the Speed button and use the keypad to enter the Corrected Speed Cal. To verify the corrected
speed cal calculated above:
a. Re-zero the distance display as in step 1.
b. Repeat step 3 and step 4. If the field computer odometer reading still does not match the distance
driven, use the new values and redo the calculation and repeat step 5.
Liquid Applications
Use the following formulas to help calculate the boom or implement section widths for either broadcast or band
applications.
Boom Cal
For liquid sprayers, the boom cal value is the width of the individual boom sections
Calculate the width of each section by measuring the spacing between spray tips in inches [cm] and then
multiplying by the number of tips in each boom section
For Example:
20 tips in a section with spacing of 40 inches would yield:
or a Section Width of 800 inches (approximately 67 feet). Enter 800 as the width for this section.
