Seed Wheel
Calibration
Section
E
The following is a list of steps to use when calibrating the seed wheel. A seed
calibration cup, funnel, stand, and scale are used to calibrate the seed wheel.
1. Set the empty seed calibration cup on the scale and zero out
the weight of the cup.
2. Place the funnel and stand in the seed to be treated or a
separate container (figure 1). This will help to avoid any
unnecessary clean-up while filling and leveling the top of the
seed calibration cup.
3. Place your hand under the bottom of the funnel and fill the
funnel up with seed.
4. Place the calibration cup under the funnel stand and remove your hand from the
bottom of the funnel, and allow the cup to be filled. (figure 1)
5. After the cup has been filled, strike off the top of the calibration cup with a straight
edge. (figure 2)
DO NOT
shake the cup.
6. Weigh the sample of seed. (figure 3)
A typical weight of the sample of seed will be anywhere between
2.8 to 4.0 lbs. Anything over or under this range could be caused by
not zeroing out the weight of the cup, or the scale may be set on the
wrong units.
