33. Weigh the containers plus seed (GrossWeight).

Subtract the empty container weights to obtain the

net weight.

34. The seed monitor assumes that all rows were tested.

If you tested fewer (commonly the case), scale the

sample size to planter-wide:

35. Enter the Amount Dispensed.

The seed monitor computes a new Spreader

Constant.

Note: If the net weight of the metered sampled was

dramatically different than expected, run another

calibration to validate or revise the new spreader

constant.

Calibrate Speed Sensor

36. Perform a Ground Speed Calibration procedure.

37. Refer to “Furrow Checking Rate” on page 31 to

verify seed rates.

For example: ContainerWeight: 2 lbs

GrossWeight: 12.88 lbs

12.88 - 2 = 10.88

NetWeight: 10.88 lbs

For example: NetWeight: 10.88 lbs

RowCount: 31

RowsSampled: 4

(10.88 × 31) ÷ 4 = 84.34 lbs

AmountDispensed: 84.34
