Accuracy Considerations
Many factors can affect the accuracy of your electronic
acremeter:
• Tire Size and Tire Pressure
The meter configuration was programmed for the tire
type and size originally provided with the drill, and
inflated to factory specifications.
• Seeding Overlap
The area reported by the meter will be higher than
the actual field area if passes overlap.
• Soil Conditions
The meter configuration was programmed for nominal
tire slippage. Extreme conditions, wet or muddy con-
ditions, min-till/no-till conditions and some native
grass conditions may change wheel slippage, result-
ing in slightly inaccurate area tallies.
Display
Liquid Crystal Displays (LCDs) do not function optimally
in extremely cold conditions (conditions colder than you
are likely to be planting in). If the display is blank, hard to
read, or sluggish, and the weather is near freezing, the
LCD is likely responding to the temperature.
The battery, rotational sensor and computer electronics
are still operating, however, and read-out will be possible
once the meter warms up. Do not use direct application
of hot air, fluids or metal to warm up the meter, or you
may damage it.
