ADVANCED SETUP / 29
HI POPULATION/LOW POPULATION
The Hi population and Low population values determine when an alarm or
row indicator displays to warn the operator about a population problem. If
the percentage (%) box is checked, the values are percentage based. For
example, 10% of 30,000 seeds/acre for the over population setting (33,000
seeds/acre) and for the under population setting (27,000 seeds/acre) (refer
to Figure 17). If the percentage (%) box is not checked, the values are
population based and expressed in 1000s of seeds per acre or hectare. The
over population and under population values are independent of each other
and do not have to be the same percentage value.
To change the percentage (%) box setting,
1. Use the Up or Down Arrow key to highlight the percentage (%) box.
2. Press the Enter key to toggle the setting from checked to unchecked.
To change the population value settings:
1. Use the Up or Down Arrow key to highlight the hi alarm or low alarm
field.
2. Press the Enter key to highlight the field for editing.
3. Use the Left or Right Arrow key to select a digit for editing.
4. When a digit is highlighted, use the Up or Down Arrow keys to edit
the value displayed.
5. Press Enter key to confirm the selection.
6. Press the Operate key to return to the Operate (main) screen.
POPULATION ADJUSTMENT
A population adjustment provides a means to display populations nearer
the actual versus the sensed seeding rates. This is useful when sensors do
not detect doubles, triples, etc.
To change the over population value setting:
1. Use the Up or Down Arrow key to highlight the field.
2. Press the Enter key to highlight the field for editing.
3. Use the Left or Right Arrow key to select a digit for editing.
4. When a digit is highlighted, use the Up or Down Arrow keys to edit
the value displayed.
5. Press Enter key to confirm the selection.
6. Press the Operate key to return to the Operate (main) screen.
POPULATION RESPONSE RATE
The population response rate is used to provide population display stability
for planters with few rows versus many or when the sensed application rate
does not match the actual application rate. Use the Population Filter to
stabilize population and alarm reporting.
To change population response rate:
1. Move the slide to the right when planting high seed rates and to the left
when planting low seed rates. (refer to Figure 17).
2. Press the Operate key to return to the Operate (main) screen.
