Speed Input Setup
Speed Input Setup is used to accomplish two objectives: to choose either true or fixed
speed and to calibrate the true speed device if used. “True” speed here indicates use
of either radar or a true wheel speed sensor; a wheel sensor is considered true speed,
however no compensation is made for wheel slippage.
The SmartBox
®
system will work in either fixed or true speed mode. The meters will
compensate for changes in planter speed only when the system is set in the true speed
mode.
The in-field calibration described below is critical for accurate speed
measurement and insecticide application. This calibration is separate from
calibrations of the radar itself; you must calibrate the speed device with the
SmartBox
®
controller by performing the 200’ in-field calibration steps stated
below. Do not enter the radar calibration number used for the other monitors. If
speed calibration is not performed correctly, then the values recorded for planter
speed will produce errors in calculations of acreage treated, pounds of chemical
applied, and pounds of chemical applied per acre. Inaccuracies resulting from
failure to properly calibrate are the responsibility of the user.
The in-field calibration routine should be used at the start of each new season or
whenever a modification is made which could affect the output of the speed sensor. For
greater accuracy, the 200’ in-field test should be run at the expected planting speed.
Also, the test should be repeated two or three times and the average count value
entered into the controller.
