Full Calibration
Make sure the seed meter cups are full, and seed can
flow at initial motor rotation. To prime the cups, see
30. Turn the console on with the ON/VR button. Check,
and as necessary, repeat step 1 through step 17.
31. Enter the amount of seed you want to measure. This
should be at least
1
/
4
of a pound (0.1 kg). Press
FUNCTION button to advance to next window.
The amount shown at right is from the example
estimate at step 2.
32. Normally, the console display informs you of the
length of time, in seconds, that the drive will be
operating, in order to meter the amount of seed you
have requested, at the calibration number, drill width,
and number of rows you have selected. Press
FUNCTION button to advance to next window.
33. If the screen reads instead:
TIME TOO LOW, or
TIME TOO HIGH,
change the amount of seed that you will count or
measure. For calibration accuracy, the Controller
firmware does not allow calibrating at settings that
would result in the drive rotating for less than 4
seconds, or more than 255 seconds.
Press FUNCTION button to return to step 30.
If modest adjustments to the sample size continue to
result in HIGH/LOW errors, chances are some other
parameter is zero or incorrect by a large factor (such
as decimal place error). To start over, press OFF, and
then ON.
