Valve Cal
Enter the appropriate valve cal value for the valve used to turn product application on or off. Raven
recommends using the following initial values for the valve cal.
These values are good starting points and will generally yield adequate results, however, the valve cal should
be refined for the individual control valves installed on your specific machine.
Note:
Refer to Appendix D, Calculating Calibrations for Liquid and Granular Applications, for more
information on calculating your valve calibration.
Valve Cal 2
This setting is currently not used. This setting must remain at zero.
Fan/Pump Cal

For the fan cal, enter the number of counts sensed in one revolution of the fan, if so equipped. For the pump
cal, enter the number of counts sensed in one revolution of the pump, if so equipped.
