BEFORE SPRAYING
CONSOLE CALIBRATION (CONT'D):
CALCULATING "RATE 1" AND "RATE 2"
Refer to the Chemical Manufacturer's instructions
on the chemical container label to determine the
application rate of the chemical to be sprayed.
Enter the application rate (with decimal) in
RATE 1 and RATE 2. Enter the rates in gallons
per acre (US mode), gallons per 1000 sq. ft. (TU
mode) or liters per hectare (SI mode) depending
on the base measurement selected. NOTE: RATE
2 should not differ more than 20% from RATE
1. If you do not use a second rate, enter the
same rate in both RATE 1 and RATE 2.
IMPORTANT: See the nozzle charts on pages
7-11 to be sure that your spray nozzles have
the capacity necessary to achieve the
application rate selected.

FORMULAS:
#
Speed (mph) =
Distance (ft.) x 60
Time (seconds) x 88
GPM per nozzle =
GPA x mph x w*
5,940
GPM per nozzle =
Gal/1000 ft x mph x w*
136
LIQUID CONVERSIONS
U.S. Gallons x 128 = Fluid Ounces
U.S. Gallons x 3.785 = Liters
U.S. Gallons x 0.83267 = Imperial Gallons
U.S. Gallons x 8.34 = Pounds (Water)
AREA
1 Acre = 43,560 sq. feet
1 Square Meter = 10.76 sq. feet
1 Hectare (ha) = 2.471 acres; 10,000 sq. meters
LENGTH
1 Millimeter (mm) - 0.039 inch
1 Centimeter (cm) = 0.393 inch
1 Meter (m) = 3.281 feet
1 Kilometer (km) = 0.621 mile
1 Inch = 25.4 millimeters; 2.54 centimeters
1 mile = 1.609 kilometers
PRESSURE
1 PSI = 6.89 kPA
GPA =
5,940 x GPM (per nozzle)
mph x w*
Gal/1000 ft. =
138 x GPM (per nozzle)
mph x w*
* w = Nozzle spacing in inches.
