When refilling a tank or bin during an application, the tank volume may be quickly reset using the Tally
Registers screen. Refer to the Tally Registers section on page 92 for information on resetting the tank volumes
to a preset value.
Rate Cal. The rate cal value is the target rate to which the system will adjust while applying the corresponding
product. Review the Rate Cal(s) section on page 33 for more information about the rate cal setting.
Note:
Refer to Appendix C, Calculating the Calibration Values, to verify the flow rate limits for the flow
mete installed in the system. Contact a local Raven or sprayer supply dealer for additional
information or assistance.
Rate Bump (+/-). The rate bump feature allows the equipment operator to quickly adjust the rate of product
application during a job. Enter the value by which the target rate will be increased or decreased when the rate
bump buttons are selected on the Application Control prompt.
See the Application Rates Area section on page 81 for more information about the Application Rates Area on
the main screen and using the rate bump feature during a field application.
Meter Cal/Density. Depending upon the selected application type, either the meter cal or product density
setting will be displayed. See the Application and Control Valve Type(s) section on page 32 for configuring the
type of product application.
For liquid product applications, the meter cal must be entered to calibrate the Viper Pro to the specific flow
meter used to measure the flow of product going to the booms. The meter cal value is typically found on the
flow meter.
For dry or granular products, enter the density or weight of 1 cubic foot of product. This value is the density of
a dry or granular product entered for rate control. Refer to the Meter Cal/Density section on page 137 and the
Spreader section on page 137 for more information on setting and adjusting the product density during a
granular product application.
Spreader. The current spreader constant value used by the Viper Pro control system. Refer to the Raven Viper
Pro Installation and Operation Manual for details on adjusting the spreader constant for the gate height or belt
travel measurements and adjustments.
Note:
Enter a value of zero for the spreader constant when applying liquid products.
