Too low - seeding rate is slow to get on target at the beginning of a pass.
Too high - seeding rate will be too high at slower travel speeds.
Aggressiveness of rate change
adjustments. Higher values will
respond more aggressively.

Prior to calibrating the Hydraulic Seed Meter, the numbers that appear in the Meter Calibration box in the Planter Control window should be similar
to the numbers that appear above. If they are not, the seed meter may be working incorrectly or the Gear Ratio may be incorrect. Contact Technical
Support for further assistance.
Percentage of seed rate error that triggers an alarm
The planter will plant at this simulated ground speed, until displayed ground speed is above this value.
Planting at the minimum ground speed will occur when any of the following conditions are met:
a) Ground speed is less than the above setting
b) Wheel motion is detected. Requires wheel motion sensor
c) Jump start switch is depressed. Requires jump start switch kit
Controller Settings - Auxiliary tab
Maximum duty cycle that can be
sent to valve without producing
any flow.
