Too many doubles or skips

What to do when a seed sensor of a precision planter counts more doubles or skips than allowed.

Doubles and skips are counted only in the “Precise” mode of seeding — on a precision planter. Each alarm is raised only if its limit is set: “Doubles error,%” and “Skips error,%” at “No” switch it off. How the window works: How alarms work.

“High % of doubles”

What it means. The share of doubles the sensor counts is higher than “Doubles error,%”.

What to check, in this order:

1. The travel speed on the panel matches the real speed.
2. “Doubles error,%” in the settings of the seed sensors — is the limit sensible? See Seed sensors and dry fertilizer sensors.
3. “Fraction” in the settings of the seed sensors. The value may have to be increased.
4. The sensor's status on its status screen — see The sensor status screen.
5. The metering unit: is it serviceable, and is it adjusted correctly?

“High % of skips”

What it means. The share of skips the sensor counts is higher than “Skips error,%”.

What to check, in this order:

1. The travel speed on the panel matches the real speed.
2. There is enough seed in the hoppers.
3. “Skips error,%” in the settings of the seed sensors — is the limit sensible?
4. “Fraction” in the settings of the seed sensors. The value may have to be reduced.
5. The sensor's status on its status screen.
6. The metering unit: is it serviceable, and is it adjusted correctly?

The stretch over which the shares are counted is “Recalculation,m” of the seed sensors. How the skips and doubles look on the diagram: The section diagram.
