Create a Controlled Material
Re-define at least one material. Otherwise, create at
least one material. Some key steps:
1. Type must be set to GRAN SEED CONTROL or
GRAN FERT CONTROL.
2. Select or Disable: Preset Method
If using preset method, select initial rate increments
that are only a few percent, so as to have fine control
of the meter scale indicator. These can be changed
to coarser increments after calibration.
3. Density must be accurately entered.
4. #Outlets or #Towers is the number of outlets per
meter, and is always “4” for NTA607/2007, whether
single- or double-shoot.
5. Enter the Cal Const if one is available for your seed
type. This value does not affect the calibration
process, and is replaced during calibration, but is
useful for comparison. The calibration constant
developed during calibration should be similar to the
seed rate chart number.
6. Set Variable Cal Const if one is available for your
seed. This is from a list of names pre-programmed
into the monitor software. It is usually not the same
name as the material name setup on page 72. In this
example, “Wheat 2S”, the “2S” refers to the (factory
standard) “2 star” meter flute configuration.
Pick a seed constant closest to yours in terms of
physical seed characteristics and meter flute
configuration.
If a suitable Variable Cal Const is available, the
system can more accurately compensate for manual
calibration cranking speeds that differ from field rate.
If no suitable Variable Cal Const is available, set to
Disabled, and crank at an rpm near field speed at
step 36.
