12. Use /
arrow keys to set Calibration number.
If no sample-based calibration is desired, press
FUNCTION to cycle to initial screen.
13. Press Function button until the Calibration window
appears as shown.
14. Press arrow button to enter calibration mode.
15. This is the first window that appears in Calibration
mode. Press FUNCTION button to accept, or
button to change units of measure.
ENGLISH (U.S. Customary) units are:
pounds/acre, pounds, feet and mph
METRIC units are:
kg/hectare, kilograms, meters and kph
If you change units of measure for rate calibration, it
also changes units for speed calibration.
When units of measure is changed, all previous and
subsequent values entered or computed are
assumed to be in the new units, but their numeric
values are not converted.
For example, if you entered a rate of 50.0 (intending
lbs/ac) at step 9, and switched to metric mode at
step 15, the seed rate is left at 50.0 and taken to be
50.0 kg/ha during any calibration and planting.
Which changing units of measure, be sure to re-check
all other settings, and convert any as required.
