3. Channel Setup Screen
Channel 1 setups are for the front hopper.
Channel 2 setups are for the rear hopper.
“Type” - Set this to either “Gran Seed Monitor” or
“Gran Fert Monitor” based on the type of material in each
hopper.
“Material Name” - Choose the name of the material
configured for each channel in steps 1 and 2 above.
“Sensor Constant” - [ 360 ]
“Gear Ratio” - [ 1 ]
“Channel Width” - is your Implement Width (swath) in
cm (inches). Precise row/swath data is found in the air
cart or implement Operator Manuals.
If the monitor inputs are correctly entered, the monitor is
a handy tool for fine-tuning the variable rate gearbox
setting. If the rate reported by the monitor does not
match the target planting rate, rotate the crank to adjust
the variable rate gearbox control arm slightly so as to
achieve the target planting rate.
Consult the DICKEY-john
®
manual for how to configure
reporting and alerts.
Meter Rate Adjustment
Seed rate is determined by:
• seed meter Final Drive Range gearing
• Variable Rate Gearbox setting
The Seed Rate Charts are based on cleaned untreated
seed of average size and test weight. Many factors affect
meter rates including foreign material, seed treatment,
seed size, field conditions, and test weight.
Minor adjustments will be needed to compensate for
these factors. Initially set the rates according to the
charts, then calibrate for your material and conditions.
Calibration is also required to set up the monitor
Calibration Constant. With the correct Calibration
Constant and material density the monitor can be used
to help fine tune the variable rate gearbox setting.
