Refer to Figure 67
41. A new calibration number is suggested, along with
the old calibration number.
Refer to Figure 68
42. 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.
Refer to Figure 69
43. Console window displays the calibration number you
have selected.
The console is once again at step 9. 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 18 through step 29.
Rate calibration results, once accepted by you, are
stored until changed, and are not lost when power is
removed.
Note: 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.
