43. Press FUNCTION button to advance to the choice
window.
If you wish to keep the old number, perhaps to re-run
the calibration procedure, press the
Down arrow
button.
To accept the New calibration number, press the
Up arrow button.
44. Console window displays the calibration number you
have selected.
The console is once again at step 10. If the
calibration just completed resulted in a Cal number
change of more than a few percent, validate or
further refine it by running a new calibration, skipping
the Priming step 19 through step 30.
Rate calibration results, once accepted by you, are
stored until changed, and are not lost when power is
removed.
Cautious practice includes a furrow inspection to
ensure that actual seed placement and spacing is as
expected. This can be done by setting one or more
rows to shallow operation, tying up the press wheel
(or locking up a 10HD row), for a short distance.
Speed Calibration
In order to fine-tune the default speed calculation or to
convert to radar speed signal, the controller may be
calibrated as follows:
1.
Set two flags 400 feet apart (100 meters if in metric
mode).
2.
To calibrate the Controller for speed, press the
FUNCTION button until the screen at right appears.
